[mpich-discuss] mpich-3.2a for Blue Gene /Q omits spi libraries from the wrappers

[William Scullin]

When building mpich-3.2a for Blue Gene /Q and following the same
procedure used for building mpich-3.1.2 for BG/Q, the required linking
information for spi and pami is omitted from the wrappers. I'm not
sure if this is intentional or not.

Thanks,
William


Patching the wrappers to reflect the required linking gives the following diff :
