fixes #i111496# (meta), #i111498# & #i111500#
(along with the similar commits to the other repos)

please guys'n'gals:
Use dmake create_patch when updating/creating new patches. And when
replacing patches instead of adding ones, use solenv/bin/patch_sanitizer.pl

Yeah, just build all the unneeded stuff (the executables like the
msgfmt command and their support libraries) in this case too, for
now. (We obviously won't be able to run ppc exectuables when
cross-compiling from Intel Mac.)

Ugh, the patch for libpng is silly, but I didn't bother now fixing the
silliness, just added the case for iOS, too.

AKA: fix compiling libcroco against SDK-libxml (Mac)

Especially not now with --disable-modules.

Pass the -I options needed in CPPFLAGS, not CFLAGS.  Explicitly
disable dynamic loading of loaders. Pass an explicit list of loaders
to build in statically. Do include the jpeg loader.
