gcc -print-search-dirs gives directories outside /tools directory

Description

While creating a x86 toolchain using lfs as a guideline, I noticed that a "gcc -print-search-dirs" on my temporary toolchain printed out some undesirable results. It contained references to /usr/... and others that I had assumed was handled by the gcc 4.1.2 spec patch.

I dug in a little and found that gcc/gcc.c still had explicit hardcoded values for standard_exec_prefix_1 and standard_exec_prefix_2. Additionally STANDARD_STARTFILE_PREFIX_1 and STANDARD_STARTFILE_PREFIX_2 were also hardcoded although these were predicated on some conditional. I found changing these references to "" removed the references to outside the /tool directory.

Confirmed.

If the OP's analysis is correct, this will be the fix: 

sed -i -e 's@/usr/libexec/gcc@@' \
       -e 's@/usr/lib/gcc@@' \
       gcc/gcc.c

I'll drop it in tonight and report back tomorrow.

Okay..not enough.

It is not only coming from gcc/gcc.c.

I'm at a loss for the moment. I'm also concerned about changing too much in our temporary tools this close to release. Pushing it off for 7.0. I'm not sure what the impact is if we adopt the cross-tools method for 7.0. Ideally, it should never get that far, however...
