Yes, adjusting your PATH is the first point noted at
https://gcc.gnu.org/wiki/CompileFarm for building GCC on AIX:

To build trunk on powerpc-ibm-aix (AIX):
- PATH=/opt/freeware/bin:$PATH
- .../src/configure --disable-werror --enable-languages=c,c++
--with-gmp=/opt/cfarm --with-lbiconv-prefix=/opt/cfarm
--disable-libstdcxx-pch
- make SHELL=/bin/bash CONFIG_SHELL=/bin/bash

I think the /scratch disk is faster, but not guaranteed to be
persistent across reboots. I did:
mkdir /scratch/$USER
ln -s /scratch/$USER ~/scratch
