 This hack cures the powerpc64-linux -frepo failures.  It should be
 safe enough to always drop a leading '.' rather than making this
 target-dependent, I think, but if this makes people nervous I'll
 introduce another #ifdef.
 
 	* tlink.c (scan_linker_output): Drop leading '.' from symbol names.
 
 OK for mainline and 3.3?
