thanks, fixed.

--with-target-bdw-gc=/opt/bdw-gc,32=/opt/bdw-gc32

sets the include and lib dirs by appending include and lib to the paths. If you
have options --with-target-bdw-gc-include= and --with-target-bdw-gc-lib= as
well, it overrides the settings done in --with-target-bdw-gc=. This is copied
from the setting of the gmp/mpfr options.

Any of these options override the automatic discovery using pkg-config.

Please suggest a better wording; I thought that was clear enough (and better
than the undocumented --enable-libobjc-gc anyway ;)
