Remove arm tests that don't compile

Upstream-Status: Pending

Corrects the original commit for the patch that removed ARM ptest CFLAGS
settings. Since the flags could be set by a user, the flags should
be kept in place during compilation.  By keeping the original up-stream
CFLAGS for the tests, then additional tests successfully compile
for all tested ARM tunings.

However, there were still two tests listed below that did not compile
for any beaglebone tuning that is valid for valgrind. With the updated
patch, the set of excluded ARM ptests and their respective build
failures are:
  intdiv - fails for all beaglebone tunings with 2 errors:
  {standard input}:(40 or 41): Error: selected processor does not
       support Thumb mode `udiv r3,r9,r10'
  {standard input}:(72 or 73): Error: selected processor does not
       support Thumb mode `sdiv r3,r9,r10'

  vcvt_fixed_float_VFP - fails for all beaglebone tunings in one of
  two ways:
    with neon tuning (-mfpu=neon) fails with Internal Compiler Error
    without neon tuning fails with 3 errors:
    {standard input}:33: Error: selected FPU does not support
      instruction -- `vcvt.f32.s32 s15,s15,#1'
    {standard input}:58: Error: selected FPU does not support
      instruction -- `vcvt.f32.s32 s15,s15,#32'
    {standard input}:136: Error: selected FPU does not support
      instruction -- `vcvt.f32.u32 s15,s15,#1'

After applying this commit, the valgrind ARM ptests compile without
errors for tunings:
  armv7[t][hf][b][-neon] cortexa8[t][hf][-neon]
where the tuning [option] was successfully compiled, both with
and without the 'option', and in combination with all other options.
