Have you recreated generated-configure.sh?

Yes, please regenerate generated-configure.sh and retry. For your
convenience I've attached my new generated-configure.sh to this mail.

Yes, I know but that's not enough. The error you reported in that mail
("This will fail by claiming *** No rule to make target
`<snip/>/jdk8/build/aix-ppc64-normal-server-release/jdk/lib/ppc64/server/jsig',
needed by `all'. Stop.") is occurs because the build doesn't know the
shared library endings on AIX (i.e. it looks for 'jsig' instead of
'jsig.so'). This is fixed by the snippet I posted in my previous mail but
that's just a starting point as well. We have to set all the required xlc
options in toolchain.m4 to get further. The bad thing is that some options
(e.g. -MMD -MF) are set unconditionally in toolchain.m4 and then refined
based on plattform and compiler. So if we do nothing, the xlc build on AIX
uses these options and that's why it currently fails.

So I'll start with the compiler settings for xlc in toolchain.m4
