I do.

...
/usr/vacpp/bin/xlc -q64 -I/home/postgres/src/include -O2 -qarch=pwr5
-qtune=balanced -qnoansialias -o cube.so libcube.a
-Wl,-bE:libcube.exp -L../../src/port -L/home/postgres/src/lib
-Wl,-blibpath:'/opt/pgsql91/lib:/home/postgres/src/lib:/usr/lib:/lib' -Wl,-bnoentry
-Wl,-H512 -Wl,-bM:SRE -lm -Wl,-bI:../../src/backend/postgres.imp
...

Further, it appears the link command pljava is using for the AIX case is
given in its makefile as...

$(COMPILER) $(LDFLAGS_NO_L) $(LDFLAGS_SL) -o $(plugin) $<
-Wl,-bE:$(NAME)$(EXPSUFF) $(SHLIB_LINK)

I can't find anywhere LDFLAGS_NO_L is defined. however, SHLIB_LINK is
defined to concatenate PLJAVA_LDFLAGS, so I set that to -lm and POOF,
its built. scary!
