cmake: Remove linker override

Browse source 
This was a workaround for an error that has been removed in glibc
2.32 (by removing sys_errlist and friends, which it complained about).

Other than that, it's an attempt at performance optimization that
should just be fixed at the system level - if your linker is bad,
replace it with a better linker. No need for fish to work around it.

Closes #8152
