Please consider adding the following diff to patch 19 to avoid this
issue (see the upstream bug report for more details):

Additionally, with older versions of clang 15.x and older, I see:

Please don't! As far as I can tell, this is what I was warning about in:
https://lore.kernel.org/linux-riscv/20230224170118.16766-1-andy.chiu@sifive.com/T/#m2c0e6128230d407c843e10406305da9ff5dca902

The randconfig has RISCV_ISA_C enabled, so you're getting an ISA string
containing "fdcv" and `fdv,,$(riscv-march-y)` fails to remove either fd,
or v.

The below is very much valid though, please test v15 with clang/llvm
Andy!
