Subject: build: Do not create .d files for gengetopt source files.
X-Git-Tag: v0.5.4~46^2~5
X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=c880740b91c17c771ddee7b3c91057f6b65946d7;p=paraslash.git

build: Do not create .d files for gengetopt source files.

The generated *.cmdline* files do not depend on headers of the source
tree, so it is pointless to let the compiler create dependencies
for them.

This speeds up make dep by 25%.
