    fix AX_GCC_X86_CPUID/AX_GCC_X86_CPUID_COUNT for 32-bit PIC compilations
    
    The problem is that the EBX register cannot be used when position 
independent code is being generated.
    The solutions to save and restore the EBX register.  See, e.g.:

    Fix second pass bug in _AX_WITH_CURSES_CHECKEXTRA

commit 302201bf1bb20543c5f3336b1a913d877e7642fb
Author: Nate Bargmann <address@hidden>

    Fix second pass bug in _AX_WITH_CURSES_CHECKEXTRA
    
    Found bug where when _AX_WITH_CURSES_CHECKEXTRA is called a second time
    on the same library, e.g. ncurses, the previous setting of
    _AX_WITH_CURSES_CHECKEXTRA_cv_var to 'yes' would be changed to 'no' just
    due to the tested header file not being available on the second pass.
    
    This was found when AX_WITH_CURSES has 'with_ncurses' set to 'yes' and
    'with_ncursesw' set to 'no' forcing _AX_WITH_CURSES_CHECKEXTRA to be
    called twice in succession since ax_cv_curses_which is set to 'ncurses'
    and the panel.h header file is tested as ncurses/panel.h and panel.h.
    
    The system in question is OpenSuSE LEAP 42.1 which installs
    /usr/include/ncurses/panel.h and not /usr/include/panel.h.
