- added to configure some detection on how to compile .s/.S with --noexecstack (or similar), as compilers' defaults are often insane - since no-execstack handling is now in build, remove .note.GNU-stack section markers (were of limites use, anyways, b/c unportable or implemented inconsistently across platforms) - some ToDo, etc. updates
