Bug#1101683: firefox: Please use alternative linker on ppc64 as lld is unsupported

Source: firefox
Version: 136.0.3-1
Severity: normal

Hi,

firefox currently fails to build from source on ppc64 since the linker
in use (lld) does not support ppc64 with ELF ABI version 1 [1]:

checking what kind of list files are supported by the linker... 
DEBUG: Creating `/tmp/conftestj70e_oyy.c` with content:
DEBUG: | int main() {}
DEBUG: Executing: `/usr/bin/clang /tmp/conftestj70e_oyy.c -c -o /tmp/conftestvirsugve.o`
DEBUG: Executing: `/usr/bin/clang -fuse-ld=lld -o /tmp/conftestvjo35x09.out -Wl,@/tmp/conftestw9ckkapq.list`
DEBUG: The command returned non-zero exit status 1.

ERROR: Couldn't find one that works

Switching to ld.bfd or mold with passing "-fusing-ld=" to clang should fix the problem.

Thanks,
Adrian
