STARTFILE_PREFIX_SPEC was added to fix-up the problems with multi-libed
targets but turned out there was a better way to fix the problem and was
basically unused within 4 months.
Reference:
<http://gcc.gnu.org/ml/gcc-patches/2002-05/msg01660.html>: The patch which
added it
<http://gcc.gnu.org/ml/gcc-patches/2002-09/msg01218.html>: The patch which
made it useless.
The last use was removed (which I cannot find the gcc-patches message for):
2003-08-23 Richard Sandiford <rsandifo@redhat.com>
* config/mips/linux64.h (STARTFILE_PREFIX_SPEC): Remove.
This patch removes STARTFILE_PREFIX_SPEC and I will close PR 19353 as
willnotfix. OK? Bootstrapped and tested on powerpc-darwin.
