be disabled for cygwin, for consistency and for the same reasons
as for win32/mingw.

Other dimensions would not work correctly currently,
also ask for a sample for files that fail this check.

This fixes an integer overflow leading to out of array
accesses.

The assembler may insert nopl instructions for cpunop, which are not
(universally) supported on i586 CPUs.

The goal is to make the capapility slightly more general and have it
cover the availability of the nopl instruction in addition to cmov.

This was due to a miscomputation of s->cur_channel, which led to
psy-based encoders using the psy coefficients for the wrong channel.
Test sample attached on the bug tracker had the peculiar case of all
other channels being silent, so the error was far more noticeable.

These platforms do not have any notion of PIC. On some compilers,
enabling pic produces a number of warnings.

This avoids trying to produce PIC loads in the ARM assembly - there
are no relocation types in PE/COFF that correspond to
BFD_RELOC_32_PCREL (R_ARM_REL32 in ELF).

As a side-effect, this avoids enabling PIC on mingw64, getting rid
of the warnings about PIC not having any effect on that platform.

This allows it to be overridden, either by the user on the command
line, or by other sections of the configure script.
