Subject: build: Compute CC version, build date and uname string only once.
X-Git-Tag: v0.5.6~83
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=e080d112e6a79c3f78c33d004010bff03b40b38d;hp=74322f0fab30777d8e34486fce1d81d4bc1106a0

build: Compute CC version, build date and uname string only once.

This should speed up the build somewhat, and it gets rid of a pointless
duplication in the Makefile.
