Compiling the j2se on Solaris 11 X86 can cause a compiler failure:

ube: error: Assert has been violated at '/set/venus/builds.intel-S2/nightly.Thu/intel-S2/lang/ube/opt/src/cfg.c 4133'.
cc: ube failed for ../../../src/solaris/native/sun/awt/awt_Mlib.c
gnumake[3]: *** [../../../build/solaris-i586/tmp/sun/sun.awt/awt/obj/awt_Mlib.o] Error 2

We may want to workaround this compiler bug (6343678) temporarily. I suspect it will be fixed in a compiler patch very soon, but if not people could easily run into this problem.

Adding a -g to the compile line fixes it.

See the suggested fix, which adds the ability to add specific compiler options per .o file, a nice feature to have anyway.
