Boost compilation fails with too many input files on AIX7.2

[bergen288]

I am trying to compile boost_1_73_0 on my AIX7.2 server. The default compiler is gcc8.3.0. However, bootstrap.sh says gcc doesn't support C++11 while it also gives list of toolsets including gcc. See attached bootstrap.log.
bootstrap.log

If I run build.sh inside tools/build/src/engine, it won't complain about gcc, but it gives me "cpp: fatal error: too many input files".

compilation terminated.

Can you please help me to figure out what's wrong?
