wip/cross-pio-gccarmnoneeabi-1.70201.0

[mlh%goathill.org@localhost (MLH)]

I have been trying to get platformio ported to netbsd lately (with much very
patient help from Thomas). I need to get cross-pio-gccarmnoneeabi-1.70201.0
building in order to support the esp32 platform.

I started working on wip/cross-pio-gccarmnoneeabi-1.70201.0 but don't know
how to build in that environment that arm has set up and could use some help.

I committed wip/cross-pio-gccarmnoneeabi-1.70201.0 to hopefully get some eyes
on it.

During the build, when the build tree is expanded:
...
wip/cross-pio-gccarmnoneeabi-1.70201.0/default/gcc-arm-none-eabi-7-2018-q2- update

How-to-build-toolchain.pdf  is the same as this:
https://github.com/vanbwodonk/gcc-arm-embedded-build-armhf/blob/master/How-to-bu
ild-toolchain.pdf

Nothing works in this environment and I can't find an example of
how to do this in /pkgsrc/cross

Do you know of something that works this way I can compare with?

Thanks
