[Buildroot] [PATCH 1/1] toolchain/wrapper: fix building without glibc

toolchain-wrapper.c now uses program_invocation_short_name, which is
a glibc specific extension. This causes build to fail when using a
system with libc different than glibc (musl, BSD libc, etc.)
This change makes toolchain-wrapper.c portable, by setting it's value
to getprogname() when __GLIBC__ is not defined, and thus makes running
buildroot possible on glibc-less systems.
