This also needs some change to the sims.
I see failures like this with git master:
make[4]: Entering directory '/home/tromey/gdb/build/sim/bpf'
CCLD run
../../bfd/libbfd.a(compress.o):compress.c:function decompress_contents: error: undefined reference to 'ZSTD_decompress'
../../bfd/libbfd.a(compress.o):compress.c:function decompress_contents: error: undefined reference to 'ZSTD_isError'
(unknown):176: error: undefined reference to 'ZSTD_compress'
(unknown):179: error: undefined reference to 'ZSTD_isError'
collect2: error: ld returned 1 exit status
You'll see them all if you do a build with all sims enabled.
thanks,
Tom
