Execution of gcc -B/usr/bin/ failed!
The script has found some problems with your installation!
Please read the FAQ and the README file and check the following:
- Did you change the gcc specs file (necessary after upgrading from
  Linux libc5)?
- Are there any symbolic links of the form libXXX.so to old libraries?
  Links like libm.so -> libm.so.5 (where libm.so.5 is an old library) are wrong,
  libm.so should point to the newly installed glibc file - and there should be
  only one such link (check e.g. /lib and /usr/lib)
You should restart this script from your build directory after you've
fixed all problems!
Btw. the script doesn't work if you're installing GNU libc not as your
primary library!
