The fact that your toolchain files seem only to be installed under /bgsys/drivers/toolchain/V1R2M0-efix23 is very different from every other BG/Q system I've seen. Normally, the toolchain files are also in /bgsys/drivers/ppcfloor so that /bgsys/drivers/ppcfloor/gnu-linux also exists (with a powerpc64-bgq-linux/lib subdirectory).

Do you have plans to install the V1R2M1 driver? (or at least the gcc 4.7.2 toolchain corresponding to that driver in /bgsys/drivers/toolchain/V1R2M1_base_4.7.2)?
