r13425: Revert all the "clever" compiler options checks. They broke

the build on Solaris, AIX and S390. The fundamental problem is
that macros like AX_CFLAGS_IRIX_OPTION can spuriously succeed.

-dnl @synopsis AX_CFLAGS_GCC_OPTION (optionflag [,[shellvar][,[A][,[NA]]])
-dnl
-dnl AX_CFLAGS_GCC_OPTION(-fvomit-frame) would show a message as like
-dnl "checking CFLAGS for gcc -fvomit-frame ... yes" and adds
-dnl the optionflag to CFLAGS if it is understood. You can override
-dnl the shellvar-default of CFLAGS of course. The order of arguments
-dnl stems from the explicit macros like AX_CFLAGS_WARN_ALL.
-dnl
-dnl The cousin AX_CXXFLAGS_GCC_OPTION would check for an option to add
-dnl to CXXFLAGS - and it uses the autoconf setup for C++ instead of C
-dnl (since it is possible to use different compilers for C and C++).
-dnl
-dnl The macro is a lot simpler than any special AX_CFLAGS_* macro (or
-dnl ac_cxx_rtti.m4 macro) but allows to check for arbitrary options.
-dnl However, if you use this macro in a few places, it would be great
-dnl if you would make up a new function-macro and submit it to the
-dnl ac-archive.
-dnl
-dnl   - $1 option-to-check-for : required ("-option" as non-value)
-dnl   - $2 shell-variable-to-add-to : CFLAGS (or CXXFLAGS in the other case)
-dnl   - $3 action-if-found : add value to shellvariable
-dnl   - $4 action-if-not-found : nothing
-dnl
-dnl note: in earlier versions, $1-$2 were swapped. We try to detect the
-dnl situation and accept a $2=~/-/ as being the old option-to-check-for.
-dnl
-dnl also: there are other variants that emerged from the original macro
-dnl variant which did just test an option to be possibly added. However,
-dnl some compilers accept an option silently, or possibly for just
-dnl another option that was not intended. Therefore, we have to do a
-dnl generic test for a compiler family. For gcc we check "-pedantic"
-dnl being accepted which is also understood by compilers who just want
-dnl to be compatible with gcc even when not being made from gcc sources.

-dnl
-dnl Try to find a compiler option that enables most reasonable warnings.
-dnl This macro is directly derived from VL_PROG_CC_WARNINGS which is
-dnl split up into two AX_CFLAGS_WARN_ALL and AX_CFLAGS_WARN_ALL_ANSI
-dnl
-dnl For the GNU CC compiler it will be -Wall (and -ansi -pedantic)
-dnl The result is added to the shellvar being CFLAGS by default.
-dnl
-dnl Currently this macro knows about GCC, Solaris C compiler,
-dnl Digital Unix C compiler, C for AIX Compiler, HP-UX C compiler,
-dnl IRIX C compiler, NEC SX-5 (Super-UX 10) C compiler, and Cray J90
-dnl (Unicos 10.0.0.8) C compiler.
