Build system fails

[nodebotanist]

The build system is attempting to reach files that no longer exist and as mentioned in #78 uses the -rc2 packages, which we shouldn't.

I am working on changing what needs to be changed to build on Linux (Ubuntu 18.04) successfully.

@rwaldron @johnnyman727 Any tips on what's needed to build openwrt-tessel?

Issues found so far when removing -rc2 from the version of openwrt:

• [SOLVED] The ccache version we were using (3.1.9) didn't have a file on OpenWRT source anymore. I updated the version to 3.1.11 and the md5 hash accordingly
• something about the following checkfor git-core in include/prereq-build lines 146-147 fails:

  $(eval $(call SetupHostCommand,git,Please install Git (git-core) >= 1.6.5, \
      git clone 2>&1 | grep -- --recursive))
  

  even though when I run git --version I get 2.7.2. Commenting it out lets the build continue.
• Line 27 of openwrt/tools/automake/Makefile throws a regex error that I'm having trouble debugging: mostly because commenting it out seems to allowed the build to continue and then even when I un-commented it the build ran past that point.
• Currently dealing with the following error, I think I'm getting close to the end:
  Can't locate /home/nodebotanist/openwrt-tessel/openwrt/build_dir/host/automake-1.15/bin/aclocal at /home/nodebotanist/openwrt-tessel/openwrt/build_dir/host/automake-1.15/t/wrap/aclocal-1.15 line 31. Makefile:2470: recipe for target 'aclocal.m4' failed

I'd like to figure out what the issue is and fix it rather than leave these commented out. Looking into it.
