From: Martin Hundebøll Date: Tue, 2 Apr 2024 08:17:38 +0000 (+0200) Subject: Makefile: preserve --jobserver-auth argument when calling ninja X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d1ce2cc95b71f41860bdff6f81c333cec11eae80;p=qemu.git Makefile: preserve --jobserver-auth argument when calling ninja Qemu wraps its call to ninja in a Makefile. Since ninja, as opposed to make, utilizes all CPU cores by default, the qemu Makefile translates the absense of a `-jN` argument into `-j1`. This breaks jobserver functionality, so update the -jN mangling to take the --jobserver-auth argument into considerationa too.
