Subject: Makefile: remove the graphs/ dir on 'make clean'
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4a9a21b95c7c4793182e8e7f0e6b70d8221eef04;p=buildroot.git

Makefile: remove the graphs/ dir on 'make clean'

Currently, a 'make clean' leaves the graphs/ subdirectory in the
output directory. This commit defines a GRAPHS_DIR variable, used by
the different graph-generating targets, and which gets cleaned up in
the 'clean' target.

[Thomas: use the new GRAPHS_DIR variable in more places, as suggested
by Yann.]
