Tried to organize the configure(env) calls in sections, using the same order
for all platforms whenever possible.
Apart from cosmetic changes, the following issues were fixed:
- Android: cleanup linkage, remove GLESv1_CM and GLESv2
- iPhone: Remove obsolete "ios_gles22_override" option
- OSX:
* Fix bits detection (default to 64) and remove obsolete "force_64_bits" option
(closes#9449)
* Make "fat" bits argument explicit
- Server: sync with X11
- Windows: clean up old DirectX 9 stuff
- X11:
* Do not require system OpenSSL for building (closes#9443)
* Fix typo'ed use_leak_sanitizer option
* Fix .llvm suffix overriding custom extra_suffix
