f54b55058a configure: Rename cmov processor capability to i686 
The goal is to make the capapility slightly more general and have it
cover the availability of the nopl instruction in addition to cmov.

e08c946c68 configure: Explicitly disable PIC when targeting win32/mingw 
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.

b1803c79dc configure: Use enable_weak when enabling pic 
This allows it to be overridden, either by the user on the command
line, or by other sections of the configure script.

94235f2ba2 indeo3: avoid writes without necessary alignment in copy_cell() 
Cells starting at a position aligned to 8 pixels but wider than
4 blocks are copied with 3 blocks per loop. This creates problems on the
next loop iterations since the routine copying 2 blocks requires the
same alignment on some architectures like ARM NEON.

2cca96e670 configure: Check for getenv 
When targeting the "windows store application" (metro) API subset
(or the windows phone API subset), the getenv function isn't
available. If it is unavailable, just define getenv to NULL.

The check uses check_func_headers, since the function actually
might exist in the libraries, but is hidden in the headers.

The fallback is in config.h since msvc can't do -D defines with
parameters on the command line, and it's used both within the
libraries and the frontend applications (so a libavutil internal
header wouldn't be enough).
