[PATCH 2/2] tools: build: Fix bashisms in run.sh

[Petr Vorel]

Fix bashisms:

* exit -1 converted to 255 (exit|return with negative status code is not
  supported on some shells)
* 'function' is useless

This fixes problems on dash, busybox ash or any other strictly POSIX
compatible shell.

Fixes: c819e2cf2eb6f ("tools build: Add new build support")
