Jan-Marek Glogowski ed1aa172f8 Unify condition names and fix "else" paths
Drop Build prefix and settle on Lib and Exe prefixes. Also add a
note about the "else" part of the condition and fix offenders.
While at it, define COND_LIB_SAL_TEXTENC to be used by sal to
prevent diverting coditions in build and cxx code.
