Subject: [PATCH 07/17] Makefile: Don't run genbuild_h if not doing a build
|
||
|
|
|
||
|
|
genbuild_h was being run on every make invocation - clean, distclean,
|
||
|
|
etc. to get the source date epoch value. This value isn't used unless
|
||
|
|
a build is being done, so don't run it on non-compile make invocations.
