[OE-core] [PATCH] libgcc: Add missing dependency on libc:do_package

[Richard Purdie]

do_package writes out shlibs data and libgcc can depend on the values
there. We therefore need to express the depdency so that sstate can account
for it for example.

Without this a version change in eglibc can "psersist" in the sstate cache
and corrupt builds.
