Here's what i pushed for this one.

I see no further gdb.compile failures.

commit 8ce74153537add5e364865518a72194ab58b3dbc
Author: Luis Machado <lgustavo@codesourcery.com>

    Force language to C in gdb.compile/compile-ifunc.exp
    Due to the lack of debug information in the binary, GDB is unable to figure
    out what language is being used.  This may be a problem when doing remote
    debugging and the binary stops at the entry point containing asm code.
    In this case GDB will switch to asm as current language and will not switch
    back to C when it reaches main, which in turn causes the compile feature check
    to malfunction.
    This is solved by forcing the language to C after reaching main.
