No, sorry.

Our Makefiles must work on all platforms (including other Unixes,
Windows, VxWorks and other embedded system). Currently, the Makefiles
use the C compiler for compiling and ld for linking.

Starting to use the C compiler for linking will probably not work
for some platform, so that is not an option.

The best way to solve the problem would of course be to choose whether to use
gcc or ld for linking on a platform-by-platform basis, but that would
require changes to configure.in and many Makefiles in source code and a lot of
time for testing.

This is not something we can do for a patch release. Maybe for R11B,
if it gets high enough priority.
