    libc: Add __errno_location() for language binding benefits.
    
     Some languages have restrictions when it comes to C style TLS handling
     (thread local might be feature-gated) or simply it is inconvenient to
     add various OS specific binding wrappers just to access C errno values.
    
     The __errno_location() symbol provides externally callable version of
     __error() inline function.
    
     While there, add __WANT_NO_INLINED___ERROR guard for few python parsers
     in DPorts that are unable to parse inlined __error() code yet.
