Configure the makefiles to work with Sun Studio compilers for Linux. This would allow us to compare Linux builds with the two compilers and determine is performance could be improved by using the Sun compilers.
Please, see the webrev hs_sscc.Nov28.tar.gz with suggested fix in attachments.
The fix has been prepared by the Sun Studio Compilers Team (Vladimir Klimov).
The USE_SUNCC macro must be passed to gnumake to build VM
with the Sun Studio Compilers.
Original versions of webrevs from Vladimir Klimov:

- Final webrev where the SPARC_WORKS macro is used instead of
__SUNPRO_C and __SUNPRO_CC:
