[Buildroot] [PATCH] toolchain: include C libraries in legal-info

[Yann E. MORIN <yann.morin.1998@free.fr>]

All,

On 2014-07-24 00:04 +0200, Yann E. MORIN spake thusly:
> So far, the legal-info infrastructure was not exporting the legal
> info for the C libraries. This is because the legal-info only acts
> on packages defined in $(TARGETS).
> 
> But the C libraries are never added to $(TARGETS), since there is no
> corresponding BR2_PACKAGE_<C-LIBRARY>.
> 
> This patch adds such symbols for the 4 C libraries we support in our
> internal backend: uClibc, glibc, eglibc and musl.

As Thomas astutely noticed, this should probably not be here... :-)

I will respin later, waiting for more reviews...
