ext-toolchain: MIPS: Select correct endianness for the target

Previously, an external-toolchain on a mipsel/mips64el target
didn't select the appriopriate endianness but
it asked the user to set the correct CFLAGS on his/her own.
We fix this by appending "-EL" to the toolchain wrapper options
if the user has selected a mipsel/mips64el target.

[Thomas: remove unneeded test on BR2_ENDIAN, since mipsel and mips64el
are always little-endian, and add the corresponding big endian case.]

toolchain-external: add missing symlink for Linaro toolchains

In 11ec38b6950 ("toolchain-external: fix Linaro ARM toolchain
support"), we fixed the support for Linaro EABIhf toolchains by adding
a /lib/arm-linux-gnueabihf -> /lib symbolic link. This is needed
because the dynamic loader looks for libraries in
/lib/arm-linux-gnueabihf rather than the usual /lib, but Buildroot
installs all libraries in /lib.

However, we forgot that the dynamic loader also loads libraries from
/usr/lib/arm-linux-gnueabihf rather than /usr/lib, so this patch fixes
that by adding the necessary symbolic link.

toolchain-external: fix visibility and length of Linaro toolchain comment

Maxime Ripard reported that the Linaro toolchains were not visible
when selecting a Cortex-A, but forgetting to set the EABI to
EABIhf. While this is expected, Buildroot should normally should a
comment in this case. However, the comment is only visible when the
selected ARM architecture is not ARMv7 *and* the EABI is not
EABIhf. Instead, make the comment visible when either the selected
architecture is not ARMv7 *or* when the selected EABI is not EABIhf.

While we're at it, reword the comment text so that it actually fits
within the limits of the menuconfig screen.

glibc, toolchain-external: copy libthread_db when gdb is enabled

As Samuel Martin noticed, libthread_db is not only needed when
cross-gdb+gdbserver is used, but also when the native gdb is used on
the target. As a consequence, this patch modifies the glibc package
and the external toolchain logic to ensure that libthread_db is copied
to the target either when the native gdb or gdbserver is enabled, by
relying on the BR2_PACKAGE_GDB option, which is enabled when native
gdb and/or gdbserver are enabled.

arch/Config.in: introduce BR2_KERNEL_64_USERLAND_32 symbol

On some architectures one can be running a 64-bit kernel with a 32-bit
userland. Such is the case for sparc64 (unsupported) for example and
mips64 with n32 ABI.

Some tools that interface directly with the kernel need to be built
specially for this, so introduce this symbol to tweak their build in
one central kludge to be future-proof.

Example: bug #6602.

Config.in files: add/update comments on (e)glibc dependencies

This patch adds missing comments about (e)glibc dependencies and updates the
text of existing comments.

Additionally, it splits dependency expressions for the touched packages from
  depends on BR2_BASE_DEP && !BR2_TOOLCHAIN_USES_GLIBC
to
  depends on BR2_BASE_DEP
  depends on !BR2_TOOLCHAIN_USES_GLIBC
so that (positive) base dependencies are separate from the (negative)
toolchain dependencies. This strategy makes it easier to write such comments
(because one can simply copy the base dependency from the actual package
config option), but also avoids complex and long boolean expressions.
