So IIUC, David is setting SHELL=/path/to/bash first, then running
configure, then getting an error. This happens because configure tests
that bash understands +=, but libtool is run with (presumably) /bin/sh and
doesn't understand += right?
If so, then if one doesn't set SHELL (or CONFIG_SHELL?) on AIX, everything
should work fine building MPC, right?
