It's a lua 5.1 vs 5.2 and 5.3 issue.

It's a complete mess because there is an uptream patch [1] that try to fixes the
build issue, but not completely.

The build fail with the following error due to compatibility mode in lua
(LUA_COMPAT_ALL and LUA_COMPAT_5_1):

lib/evas/.libs/libevas.so: undefined reference to `luaL_openlib'
collect2: error: ld returned 1 exit status

Also the patch break the build for lua 5.1...
So, I think it's safe to add a dependency on lua 5.1 and report the problem
upstream.

I think this build failure is here since we SED into the Makefile to remove the
documentation.

But I gave up on the patch for upstream...

Why not. The latest gdb version was 7.5.1 when gdb for Microblaze was added to
Buildroot. Now we have at least 7.7.x.

Yes maybe.

binutils 2.26 should be released in a few days, hopefully.

This patch should be fine:
