x86_64 is used as a baseline: the "x86_64" entry, whatever status it has,
is transformed into "all", and then the other entries in ARCHITECTURES
either dropped or rearranged appropriately.
* Mark 1.10~a as broken since there are still a few issues:
- libmupdf.so is not being built.
- libmupdfthird.a is being built but is empty.
- unlike 1.8, 1.10~a cannot be built on x88_gcc2 primary
arch because a dependency on harfbuzz was added. That
said, it might be possible to remove that dependency.
* Updated patches from 1.8 to 1.10~a.
* Added patches to fix includes for hb.h and hb-ft.h and to
skip unneeded workaround in source/fitz/load-jpx.c
* Merged/replaced old patch with one from @korli.
* Add dependency on libharfbuzz and libglib_2.0 too, as it is
required by harfbuzz.
