[Bug target/42789] New: undefined reference to `__sync_fetch_and_add_4'

["stsp at users dot sourceforge dot net" <gcc-bugzilla at gcc dot gnu dot org>]

When I try to compile the program that
ueses boost, for sh4 target, I am getting
the undefined reference errors.
I'll attach the test-case for that, you
just type "make" to see the errors.
The makefile greps the output because there
are much more undefined references to the
other components of the program that I have
not included in the archive, hope it is enough
for testing.

$ sh4-linux-gcc -v
