build

What about removing those in the driver?  This way it works correctly  
for other makefiles too?

 Currently libjava is being improperly linked (PR java/41991) due to  
 the
 presence of -lm and -lpthreads on the shared library linkages. This

 libSystem.dylib to be pushed to the front of the linkage and breaks  
 the logic
 used by libgcc_ext. We should add and set defines for  
 HAVE_LIBSYSTEM_PTHREADS
 and HAVE_LIBSYSTEM_LIBMATH to configure and use these for  
 conditionals in the
 Makefile.am's where appropriate to avoid passing -lm and -lpthread  
 on darwin.

proposed patch to add and use remove-outfile

The proposed patch implements remove-outfile to parse out -lm and -lpthread
from LINK_SPEC in darwin.h.

Note that while the proposed patch properly parses out -lm and -lpthread from
linkages done with the compiler, this is insufficient to solve the problems
with libjava. The hard coded use of -lm in libjava/Makefile.am has to be fixed
as well since this links directly with ld via libtool.
