Add gcc-8.1.0 support to buildman toolchain.

The old gcc-7.3.0 has shared libraries issues on Ubuntu 18.04LTS and
19.04.

Though both 7.3.0 and 8.1.0 have arc and nds32 compilers, the following
errors were generated on Ubuntu 19.04.

For the x86 failure, it is a known regression issue of GCC 8.

We should fix all issues before we turn on the 8.1 for buildman,
otherwise the travis-ci will break.

Unfortunately the kernel.org gcc-8.1 toolchain just isn't usable for us
due to a number of later-fixed regressions.  We need to use gcc-8.3, I
think, for something that should work again everywhere.  And when I last
looked (mid-May, from my WIP branch) while I could get gcc-8.3 for ARM I
couldn't find one for x86.  The Bootlin toolchains are only 8.2 and
that's not new enough to have the problem Bin notes as a regression
fixed.

Can you not resolve those shared library issues via one of the toolchain
PPAs ?

I switched to Fedora 30, which does not have such shared libraries 
issues. Fedora has more cross compiler supported, with gcc-9. I am 
trying them, and will feedback later.
