Subject: [PATCH i2c-tools v2] allow to preset custom CFLAGS and LDFLAGS
Date: Fri, 7 Aug 2020 13:12:30 +0200 [thread overview]
Message-ID: <20200807111230.1241-1-wsa@kernel.org> (raw)
Sometimes I need to add some flags (like -static for the linker), so
allow this for all CFLAGS and LDFLAGS used in this project.
