>Description:
src/external/gpl3/gcc/dist/gcc/configure doesn't quote the value of
gcc_cv_ld properly so when that value contains spaces, configure
probably misdetects a bunch of ld-related features.  configure has a
bunch of

  if test x$gcc_cv_ld != x; then

all in all:

  $ grep 'x\$gcc_cv_ld\b' src/external/gpl3/gcc/dist/gcc/configure | wc -l
  36

so

  checking linker -Bstatic/-Bdynamic option... /home/uwe/work/netbsd/ro/src/external/gpl3/gcc/dist/gcc/configure: 25916: test: x/home/uwe/work/netbsd/build/tools/bin/sparc64--netbsd-ld: unexpected operator
  no

etc, etc...
>How-To-Repeat:
Discovered when testing the following:

$ cd compat/sparc64/sparc
$ nbmake-sparc64 BOOTSTRAP_SUBDIRS=../../../lib clean
$ nbmake-sparc64 BOOTSTRAP_SUBDIRS=../../../lib depends

observe in the output:

--- depend-libgcov ---
#    create  libgcov/auto-build.h
... gcc_cv_ld=/home/uwe/work/netbsd/build/tools/bin/sparc64--netbsd-ld\ -m\ elf32_sparc\ -m\ elf32_sparc\ -m\ elf32_sparc ... /usr/bin/sh /home/uwe/work/netbsd/ro/src/external/gpl3/gcc/dist/gcc/configure ...

...
checking how to hardcode library paths into programs... immediate
basename: extra operand 'elf32_sparc'
Try 'basename --help' for more information.
checking whether we are using gold... /home/uwe/work/netbsd/ro/src/external/gpl3/gcc/dist/gcc/configure: 23262: test: x/home/uwe/work/netbsd/build/tools/bin/sparc64--netbsd-ld: unexpected operator
no
