branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
The SWUPDATE_SET_BUILD_OPTIONS macro sets a number of swupdate
configuration options with local build details, especially the
cross-compiler path and sysroot path.
This means that if one stores an swupdate defconfig file as part of
Buildroot, generated with "make swupdate-update-defconfig", it will
contain things like:
CONFIG_CROSS_COMPILE="/home/thomas/projets/buildroot/output/host/bin/arm-linux-"
CONFIG_SYSROOT="/home/thomas/projets/buildroot/output/host/arm-buildroot-linux-uclibcgnueabi/sysroot"
which obviously are not good, as they are specific to where the build
was done.
So instead this commit:
- Uses the CROSS_COMPILE environment variable to pass the
cross-compiler path.
- Drops entirely the use of CONFIG_SYSROOT, since all it does is pass
a --sysroot option to the compiler, which is not needed in the
context of Buildroot.
- Pass EXTRA_CFLAGS/EXTRA_LDFLAGS also through the environment.
Thanks to that the swupdate defconfig file no longer contains any
local build details, and can be re-used by different users of a given
Buildroot configuration.
