[PATCH 1/2] gen_compile_commands: Ignore libgcc.a

[Thomas Weißschuh]

Some architectures link libgcc.a from the toolchain into the kernel.
gen_compile_commands trie to read the kbuild .cmd files of its
constituent object files, which are not available.

Flat out ignore libgcc.a, as it is not built as part of the kernel
anyways.
