Makefile: be silent when only GIT_USER_AGENT changes

jrn · gitster · commit 33ddbcb01208 · 2012-07-09T08:56:37.000-07:00
To avoid noise during builds, unlike the GIT-CFLAGS rule which prints
"* new build flags or prefix" so the operator knows why all files are
being rebuilt when it changes, GIT-USER-AGENT generation is silent.

If this code breaks and a target depending on GIT-USER-AGENT ends up
being rebuilt when it shouldn't be, the full dependency chain can be
retrieved with "make --debug=b".
