[Buildroot] [pull request] Pull request for branch ext-toolchain-fixes

[Thomas Petazzoni]

Hello,

Here is a patch set improving the support for external toolchains,
after testing with Buildroot x86-64 toolchain, Crosstool-NG x86-64
toolchain, MIPS and PowerPC CodeSourcery toolchains.

The MIPS CodeSourcery toolchain is not fully supported yet: it is a
very smart multilib toolchain, which supports both glibc and uclibc in
a single toolchain, with -muclibc being the gcc flag to switch to
uClibc. For the moment, only the default variant (glibc) is supported.

This patchset only touches toolchain/external-toolchain/ext-tool.mk,
except for a patch that is added to uClibc to fix fcntl64() on 64 bits
targets. This patch is already upstream in the master branch, and a
bug has been filled into the uClibc bug tracker to ask for this patch
to be merged into the 0.9.31 branch.
