 configure.ac: Allow disabling of large-address-space

 Recent changes (commit 0d1a8d09f4) for 64 bit platforms allowed GHC
 to mmap one huge (currently 1 terrabyte) memory region from which to
 do its own allocations. This is enabled by default, but it would be
 nice (even just from the point of view of testing) to be able to
 disable this at configure time.

 Test Plan: configure and grep mk/config.h for USE_LARGE_ADDRESS_SPACE
