boot: only link libgcc when compiler is gcc

When compiling in systems which do not have gcc installed
(like a musl+llvm system) the forced linkage "-lgcc" is
stopping it to compile. As when compiler is clang it do not
need to link explicitelly to gcc I've modified meson to only
link to gcc library when compiler is gcc.

Closes: #35162
