Revert "lib/oe/image.py: fix working directory"

This reverts commit 3f49597225a58965124503ca5f3cc4011b04b3c0.

This change appears to cause more problems than it fixes since the
compression commands usually work in the deploy dir but the archive ones
have always worked in the rootfs dir (which is clear from the tar command
we use).
valgrind: Add glibc 2.19 awareness

It wont compile otherwise and fail with errors e.g.

Valgrind requires glibc version 2.2 - 2.17 ...

License formatting and address for FSF in the COPYING and COPYING.LIB

Dropped patched already upstream and patches that were workarounds for
older glibc and busybox

for e500 we have should pass --without-fp to eglibc/glibc 2.19 onwards

rootfs.py: Check for LDCONFIGDEPEND being empty string

We override LDCONFIGDEPEND to be empty string for uclibc
however the current check is for it being None as a result
the function is still executed but ldconfig-native is not
built as dependency for rootfs when building with uclibc

Fixes errors like below

icu: Disable the default LDFLAGSICUDT for target compile

By default LDFLAGSICUDT=-nodefaultlibs -nostdlib for Linux
which means DT_NEEDED section for libicu will not be populated
with dependencies when we reset it to be empty then the default
libraries it needs are added to DT_NEEDED section in ELF header

This patch is a workaround as I consider it for now, since it could
be a problem in glibc dynamic loader for arm (especially for hf case)
where its unable to load shared objects which dont have any dependencies
expressed in DT_NEEDED segment.

here is when LDFLAGSICUDT=-nodefaultlibs -nostdlib

btw. ldd reveals the fist one to be static library while the second
one is detected as shared library. This could be a clue into how
elf headers are being interpreted by dynamic loader.

The data seems to be all static in libicudata which could
load it quicker and thats what could be confusing dynamic linker ..may
be

binutils: ld-is-gold should not affect native and crosssdk recipes

gold linker does not support all architectures, currently arm and x86
are best supported, therefore we can not enable this as a full distro
option where we need to support other architectures e.g. ppc, mips
currently, if we enable ld-is-gold distro feature conditionally then it
invalidates native and sdk version of native binutils because configure
option would change. With this patch we limit ld-is-gold feature to
imapact cross binutils and target binutils only. This means that we
can reuse the sdk and native versions across architectures.

image_types.bbclass: Fix tar IMAGE_CMD to not change directories

    lib/oe/image.py: fix working directory

    The working directory needs to be changed before the image creation
    commands instead of afterwards.

exposed an issue when generating tar images, where it would cd into
rootfs and then create the rootfs tarball and remain there since the
cmd to cd into deploy dir moved up the immediate following cmd like
tar.bz2 or tar.gz were still looking for tarball in current directory
which esentially was not deploy dir but IMAGE_ROOTFS instead

package.bbclass: add SHLIBSSEARCHDIRS to define where to search for shlib providers

* when package contains some files matching "^.*\.so", but in directory
  not default linker search paths (e.g. /opt/package/bundled-lib/libfoo.so)
  don't register it as libfoo provider, because it's possible that there
  is different package providing libfoo.so in ${libdir} and that would
  be better shlib provider for other packages to depend on
* recipes providing libs intentionally in some other directory can
  define own SHLIBSSEARCHDIRS value
