From: Thomas Petazzoni Date: Fri, 23 Nov 2018 14:58:09 +0000 (+0100) Subject: Makefile: move .NOTPARALLEL statement after including .config file X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=052fec0c08f6515055187c7d209663681bdf8144;p=buildroot.git Makefile: move .NOTPARALLEL statement after including .config file In a follow-up commit, we will make the .NOTPARALLEL statement conditional on a Config.in option, so we need to move it further down.
