[Committed, 3.4/mainline] Fix PR 16842 - mkheaders.in references gcc-libc

[Andrew Pinski]

With the change over to use .../lib/gcc/ instead of .../lib/gcc-lib/ in 
3.4.0,
there was one reference which was missed in mkheaders.in.
This patch which I committed as obvious to the 3.4 branch and the 
mainline
fixes that problem.

Thanks,
Andrew Pinski
