Description of problem:

  clang fails to link a simple C program because it cannot find libgcc.

  It looking for libgcc in /usr/lib/gcc/i686-redhat-linux/4.6.1
  but the files are actually located in /usr/lib/gcc/i686-redhat-linux/4.6.2

  As a workaround, you can create a symlink from 4.6.1 -> 4.6.2 like this:

     sudo ln -s 4.6.2 /usr/lib/gcc/i686-redhat-linux/4.6.1

Version-Release number of selected component (if applicable):

  clang version 2.9 (tags/RELEASE_29/final)


How reproducible:

  try to build an executable binary.

Steps to Reproduce:
1. yum install clang
2. echo 'int main() { exit(0); }' > /tmp/test.c
3. clang /tmp/test.c
  
Actual results:

/usr/bin/ld: cannot find crt1.o: No such file or directory
/usr/bin/ld: cannot find crti.o: No such file or directory
/usr/bin/ld: cannot find crtbegin.o: No such file or directory
/usr/bin/ld: cannot find -lgcc
/usr/bin/ld: cannot find -lgcc_s
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Expected results:

 An executable file named 'a.out'

Additional info:

 Here is the output of 'clang -v test.c':
