  arm: Fix SIGBUS on ARM when compiled with binutils 2.29
  
  In binutils 2.29, the behavior of the ADR instruction changed so that 1 is
  added to the address of a Thumb function (previously nothing was added). This
  allows the loaded address to be passed to a BLX instruction and the correct
  mode change will occur.
  
  See: https://sourceware.org/bugzilla/show_bug.cgi?id=21458
  
  By using adr with a label that isn't annotated as a thumb function,
  we avoid the new behaviour in binutils 2.29 and get the same behaviour
  as in prior releases, and as in other assemblers (ms armasm.exe,
  clang's built in assembler) - an idea that Janne Grunau came up with.

• Remove support for building for mingw32ce (Windows CE)

  Remove support for building for mingw32ce (Windows CE)
  
  The toolchain for this target is unmaintained since many years.
  
  While it has been continuously build tested on fate, it hasn't
  actually been tested at runtime since many, many years (and back
  then, only a few codecs in libavcodec were tested).
  
  So far, keeping support for it has been mostly effortless, but
  the compiler does seem to have issues with dllimported data symbols,
  ending up as internal compiler errors in some cases. Instead of
  jumping through further hoops to work around that, just remove the
  target.
