It looks like the package uses libtool, and probably there's some mix between
32-bit specific options and 64-bit specific options.

The 4 known working configurations [1] on this machine are:

32-bit, xlc:
CC="xlc -qthreaded -qtls"; CXX="xlC -qthreaded -qtls"; export CC CXX
unset AR
unset NM

64-bit, xlc:
CC="xlc -q64 -qthreaded -qtls"; CXX="xlC -q64 -qthreaded -qtls"; AR="ar -X 64"; NM="nm -X 64 -B"; export CC CXX AR NM

32-bit, gcc:
CC="gcc"; CXX="g++"; export CC CXX
unset AR
unset NM

64-bit, gcc:
CC="gcc -maix64"; CXX="g++ -maix64"; AR="ar -X 64"; NM="nm -X 64 -B"; export CC CXX AR NM

The variables AR and NM are needed by libtool.
