Good point. I just forgot about  svn:executable property. Fixed patch
is attached to the mail. Please review it.

This is an old gcc feature. Here is the description:
http://gcc.gnu.org/onlinedocs/gcc/Directory-Options.html

And here is a reproduction script:
$ gcc --version
gcc (Debian 4.4.5-8) 4.4.5

$ ln -s /usr/bin/as pref-as
$ ln -s /usr/lib/gcc/i486-linux-gnu/4.4.5/collect2 pref-collect2

$ gcc -Bpref- -v check.c
<snip>
pref-as -V -Qy -o /tmp/ccmc6KMn.o /tmp/ccFEghyX.s
<snip>
pref-collect2 --build-id --eh-frame-hdr -m elf_i386 --hash-style=both <snip>
