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

File:
'/home/kraj/work/angstrom-repo/sources/openembedded-core/meta/lib/oe/rootfs.py',
lineno: 191, function: _run_ldconfig
     0187:    def _run_ldconfig(self):
     0188:        if self.d.getVar('LDCONFIGDEPEND', True) is not None:
     0189:            bb.note("Executing: ldconfig -r" +
self.image_rootfs + "-c new -v")
     0190:            self._exec_shell_cmd(['ldconfig', '-r',
self.image_rootfs, '-c',
 *** 0191:                                  'new', '-v'])

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.
