The special flags are only applied when building freestanding binaries (the EFI executables, etc).

I think the flags passed there are justified:
-Os - to keep the size of the BIOS binaries small (there is an upper size limit),
-g - for stacktraces,
-fPIE - forcing PIE as that's a requirement for EFI executables,
-march=* - forcing a base ISA to avoid extensions that need to be enabled before use.

The stuff that runs under Linux (the `limine` command) is compiled with the user-supplied CFLAGS as expected.
