Fix 2nd arch for live555 & aplayer; cosmetic edits elsewhere. (#593)

* live555: Use $developLibDir instead of $developDir/lib since the
  latter is not appropriate for 2nd arch builds.
* aplayer: Drop $secondaryArchSuffix for cmd:nasm in BUILD_PREREQ.
* re2c: use tabs (instead of white spaces) in BUILD_REQUIRES.
* Remove x86_64 from SECONDARY_ARCHITECTURES for sdl2_net, edgar,
  paladin-git and mediainfo-0.7.61.
