Bug #41710: MySQL 5.1.30 crashes on the latest OpenSolaris 10
Change the default optimization level for Sun Studio to "-O1".
This is a workaround for a Sun Studio bug (see bug #41710
comments for details):
1. Use $GCC instead of $ac_cv_prog_gcc to check for gcc, since
the first one is the only documented way to do it.
2. Use $GXX instead of $ac_cv_prog_cxx_g to check for g++,
since the latter is set to "yes" when the C++ compiler accepts
"-g" which is the case for both g++ and CC.
3. When building with Sun Studio, set the default values for
CFLAGS/CXXFLAGS to "-O1", since unlike GCC, Sun Studio
interprets "-O" as "-xO3" (see the manual pages for cc and CC).
