* from pixman-0.24.4.patch drop:
  - Android support config.sub: obsoleted by new upstream autoconf
  - configure Mac OS X 10.4 (unsupported) linker warning
  - configure getisax Solaris check: it's unclear why this would
    give a wrong result on Linux, it certainly does't on Fedora 24...
  - __inline__ workaround looks fixed upstream
* drop pixman-0.24.4.android.patch:
  obsoleted by new upstream autoconf

* from cairo-1.10.2.patch drop:
  - Makefile.win32.common: drop this for now, we don't build
    cairo on windows and paths in this patch are still dmake INPATH...
  - Android support config.sub: obsoleted by new upstream autoconf
  - configure "libpng15" should be obsolete since it's overridden
    by png_CFLAGS/png_LIBS anyway
  - configure Mac OS X 10.4 (unsupported) linker warning
  - cairo-output-stream.c: fixed upstream
  - cairo-ft-font.c: presumed obsolete, FcResultOutOfMemory added in 2004
* drop cairo.dlsym.lcdfilter.patch:
  FT_Library_SetLcdFilter since 2.3.0 so exists in RHEL 6 baseline (2.3.11)
* drop cairo-1.10.2-oldfontconfig.patch:
  RHEL 6 baseline has fontconfig 2.8.0 so 2.2.95 isn't "too new"
* drop cairo-1.10.2.wntmsc.patch:
  we don't build cairo on windows currently, and this doesn't apply
* drop no-flto-clang.patch:
  fixed upstream
* remove definition of COMPRESS var that appears to be completely unused
