- revise for better compatibility with new autoconf,
- remove HP/UX 9 (%@#!) support from it,
- replace system("touch conf.esdtest") with fopen/fclose in the
test code (see, e.g. glib-2.0.m4 -- sdl.m4 does the same.)
configure output is practically unchanged. there are still lots of
AC_TRY_COMPILE/AC_TRY_LINK replacements needed to really eliminate
the warnings, but that's for another time.

I've discovered that when building on powerpc64le (and probably powerpc64) SDL's configure script fails to detect dynamic library support, causing it to build a static library. This causes link failures due to undefined symbols later when packages link with -lSDL.
This seems to be because the included autotools package is too old to detect powerpc64le. This change corrects the problem for me but newer versions of autotools should handle it without a patch
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
