AFAIK yes.  There are two issues here:

1. an error that I have downgraded to a warning because the code is
too pedantic for its own good. Unfinished diff that went nowhere:
https://reviews.llvm.org/D106378

2. compat.o has been generated with ld(1) and objcopy(1):

ld -melf64lriscv -r -b binary -o src/compat.o src/compat.luac
objcopy --rename-section .data=.rodata,contents,alloc,load,readonly src/compat.o

ld: warning: src/compat.o: cannot link object files with different floating-point ABI from /usr/lib/crtbeginS.o
cc: error: linker command failed with exit code 1 (use -v to see invocation)

ld(1) itself is at fault, llvm-readelf -Wa on such an object file gives:

  Properties:    RISC-V feature: ZICFILP-unlabeled, ZICFISS, ZICFILP-func-sig, <unknown flags: 0xfffffff8>

which looks like junk.  I have noticed this since months already but I
haven't bothered yet to go and find the root cause.
