  Hi,

... there are more effects, like stuff being enabled because 64bit devel
lib is installed even when the 32bit devel lib isn't.

IMO it is fine to expect users set PKG_CONFIG_LIBDIR accordingly in that
case.  It would be very nice though to record this variable (in
config.status maybe?) so it doesn't get lost in case make figures it
should re-run configure because it was changed.

cheers,
  Gerd
