commit 512073980d39824ebc694507be294838a4dcc904

portable: MacOS: export env from configure

Compiling -portable on MacOS directly would never have worked, as the
environment was only being set when run under CI.

Move these checks into configure.ac so that they propagate out to make,
etc.

Noticed by cjones on IRC.
