guix: disable gcov in base-linux-gcc

fanquake · fanquake · commit f6496a838828 · 2024-12-09T15:28:25.000Z
In a `x86_64-linux-gnu` build, this drops: ```bash x86_64-linux-gnu/bin/x86_64-linux-gnu-gcov x86_64-linux-gnu/bin/x86_64-linux-gnu-gcov-dump x86_64-linux-gnu/bin/x86_64-linux-gnu-gcov-tool x86_64-linux-gnu/lib/gcc/x86_64-linux-gnu/12.4.0: libgcov.a ``` For mingw-w64-gcc, `--disable-gcov` is currently passed for this target in Guix, due to issues with mingw-w64, see https://github.com/fanquake/guix/blob/8bed031e58c9cf895d243790e7c80808b0075de7/gnu/packages/gcc.scm#L99-L102. However we'll add it in any case, in case it's re-enabled in future, when the underlying issues are fixed.
