#3477 Snapshot build fails on Debian GNU/Linux testing

[Philipp Klaus Krause]

Trying to build current snapshots from trunk on a Debian GNU/Linux testing machines using the instruction at https://sourceforge.net/p/sdcc/wiki/HOWTO%20Make%20Snapshot%20Builds%20on%20the%20Developer%20Machine/ fails for me:

This is fixed with [r13729]. But more and other problems persist with cpp build, nmi.
