            Bug ID: 59321
           Summary: -fuse-ld does not have effect on -print-prog-name
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: driver
          Assignee: unassigned at gcc dot gnu.org
          Reporter: maemarcus at gmail dot com

Many configure scripts e.g. GLIBC use -print-prog-name to check the binary
utils used by GCC. Distros may face need to switch linker between bfd and gold,
which is now possible thanks to -fuse-ld flag. However, -print-prog-name is not
affected by -fuse-ld, and thus may lead to configure checks and actual build
being performed using different linkers.

$ kernelgen-gcc -fuse-ld=gold -print-prog-name=ld
/home/marcusmae/rpmbuild/kernelgen/head_llvm192445_i686-linux-gnu_x86_64-linux-gnu_debug/INSTALL/bin/kernelgen-ld
$ kernelgen-gcc -fuse-ld=bfd -print-prog-name=ld
/home/marcusmae/rpmbuild/kernelgen/head_llvm192445_i686-linux-gnu_x86_64-linux-gnu_debug/INSTALL/bin/kernelgen-ld

I think -fuse-ld should play together with -print-prog-name. In the example
above with default gold, second command should point to kernelgen-ld.bfd
