- Optimized and cleaned up the Do-rpm and Bootstrap Perl scripts

 - Enhanced Do-rpm to support building RPMs with different compilers
   and options


Build-tools/Bootstrap:
   - small optimization (use builtin Perl cwd() function instead of running
     "pwd" twice)
Build-tools/Do-rpm:
   - added options to handle different compilers and compile flags (e.g. when
     compiling on IA64 using the Intel ecc compiler)
   - code cleanups (use more builtin Perl functions instead of forking
     subrocesses)
   - don't try to probe various distribution-specific RPM options - query rpm
     directly instead
   - Pass the MySQL version as an argument, not an option (as it's not
     optional anyway)
