 See comment:ticket:44268:6 for an interesting problem with apple-gcc42 on
 Tiger PowerPC.

 It seems that when doing even quite simple compiles such as those a
 configure script does, it produces this warning:

 {{{
 ld: warning: object file compiled with -mlong-branch which is no longer
 needed. To remove this warning, recompile without -mlong-branch:
 /usr/lib/crt1.o
 }}}

 This warning, printed on stderr, in turn can cause an otherwise successful
 compilation to be interpreted by the configure script as a failure.

 I am assuming that the directive to "recompile without `-mlong-branch`" is
 supposed to be taken to mean "recompile ''/usr/lib/crt1.o'' without
 `-mlong-branch`", and is not talking about the small program the configure
 script compiled, since that compilation did not include the `-mlong-
 branch` flag to begin with.

 Is there a way that apple-gcc42 could ''not'' print that warning, at least
 not for system libraries like /usr/lib/crt1.o which it's not our bailiwick
 to fix?
