Changed defaults on Solaris and Forte to be CC and cc instead of cc-5.0

Replaced abs_top_srcdir with top_srcdir, not sure it's an
improvement but at least it's known that abs_top_srcdir
in cases have a problem and this is a more common variable
to use for the same purpose.

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 .

and sparc (and are defined empty for any other platform).

Removed instance manager from builds

Make it possible to say --compiler=SunStudio instead of

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
