toolchain/gcc: enable zstd support

Browse Source 
LTO object files will now be compressed using zstd.

Compressing debug sections with zstd will have to wait for GCC 13,
which adds support for -gz=zstd.

NOTE: wiping the ccache is strongly recommended, not doing so might
yield build error later on:
"lto1: internal compiler error: original not compressed with zstd"
