You need to do two things: 1) patch lua (see below, it basically
restores http://review.coreboot.org/#/c/8524/3/SerialICE/patches/lua-5.2.0-shared.dif...
) 2) install the package libglib2.0-dev

All this will most likely work when you have
/etc/ld.so.conf.d/libc.conf (or another file with a line
'/usr/local/lib' in it) in place.
