Use AC_TRY_RUN instead of AC_TRY_LINK when checking for x86 PAUSE instruction support, due to http://bugs.opensolaris.org/bugdatabase/printableBug.do?bug_id=6478684 .

etc.  The sparc_* are defined only for sparc, but the sun_* are generic for x86

Fixed handling of 32 and 64 bits.

Downgraded Solaris builds on Forte to use -xO2 rather than -xO3.

Made it possible to build 64-bits on Mac OS X

Fixed some bugs in setting CC, CXX, ASFLAGS, LDFLAGS

Fixed bugs relating to use of SunStudio/Forte in check-cpu

Reorganized code a bit

Removed the use of --with-fast-mutexes since they aren't really
fast, rather slow.

Added -static-libgcc when using gcc

Added optimising compilation flags on BSD

Added use of curses library on Solaris

Removed the use of MY_ATOMIC_MODE_RWLOCKS which removed use of

Added support for Forte on Solaris/x86

removed from SHOW ENGINE InnoDB STATUS

parameter innodb_thread_concurrency_timer_based is used to
