[Build-common-hackers] Bug#564662: autotools configure stamp breaks multi-variant builds

[Peter Eisentraut]

Package: cdbs
Version: 0.4.65
Severity: normal

The new stamp-autotools-configure file breaks if a package builds multiple
variants with different build directories, because all but the first variant
won't build because they use the same stamp file.  Example: bug #564399

I think this change should be reverted and users who want a nonstandard stamp
file because they use nonstandard autotools should be given a variable to
override it for their specific use.
