[Build-common-hackers] Bug#546589: python-distutils.mk uses for loops without error checking

[Peter Eisentraut]

Package: cdbs
Version: 0.4.53
Severity: important

Introduced in revision 341, the build and install targets in 
python-distutils.mk use for loops, but don't check the exit code of the loop 
body.  This means that build failures are pretty much not detected at all.
