gcc from tools fails on GNU/Linux

Hi,

I use to include my GNU/Linux machines CPUs when building
packages by using distcc.

I build the toolchain the standard way:

$ ./build.sh -j4 -m amd64 -T /home/netbsd/tools tools

This worked OOB until I upgraded some of my NetBSD machines to
NetBSD 6.0. I then upgraded the toolchain in the Linux machine
to -rnetbsd-6-0, but distcc stopped working. Digging a little bit,
I discovered that gcc was failing because it couldn't find `cc1'.
`cc1' is located here:

tools/libexec/gcc/x86_64--netbsd/4.5.3/cc1

whereas:

$ tools/x86_64--netbsd/bin/gcc -print-search-dirs
install: 
/home/netbsd/tools/x86_64--netbsd/bin/../lib/gcc/x86_64--netbsd/4.5.3/
programs: 
=/home/netbsd/tools/x86_64--netbsd/bin/../libexec/gcc/x86_64--netbsd/4.5.3/:/home/netbsd/tools/x86_64--netbsd/bin/../libexec/gcc/:/home/netbsd/tools/x86_64--netbsd/bin/../lib/gcc/x86_64--netbsd/4.5.3/../../../../x86_64--netbsd/bin/x86_64--netbsd/4.5.3/:/home/netbsd/tools/x86_64--netbsd/bin/../lib/gcc/x86_64--netbsd/4.5.3/../../../../x86_64--netbsd/bin/
libraries: 
=/home/netbsd/tools/x86_64--netbsd/bin/../lib/gcc/x86_64--netbsd/4.5.3/:/home/netbsd/tools/x86_64--netbsd/bin/../lib/gcc/:/home/netbsd/tools/x86_64--netbsd/bin/../lib/gcc/x86_64--netbsd/4.5.3/../../../../x86_64--netbsd/lib/x86_64--netbsd/4.5.3/:/home/netbsd/tools/x86_64--netbsd/bin/../lib/gcc/x86_64--netbsd/4.5.3/../../../../x86_64--netbsd/lib/

Adding a symlink in tools/x86_64--netbsd/ did the trick:

lrwxrwxrwx 1 root root 10 Dec 11 17:49 tools/x86_64--netbsd/libexec -> 
../libexec

But as this used to work before, I presume something broke.

Is this worth a PR?

Thanks,
