- Subject: [PATCH] datapath: unexport LDFLAGS
-
- OpenWrt build system will put "-specs=.../hardened-pie-ld.specs" into
- LDFLAGS when building PIE binaries. However the "-specs" argument is
- inteneded for "gcc" the driver while "ld" the linker when presented will
- complain it as unrecognized error.
-
- This can cause Kbuild error when building datapath kernel modules. The
- issue should only happen when compiling against upstream kernel 4.14 and
- earlier. Later ones should have been fixed with kernel upstream commit
- d503ac531a5 ("kbuild: rename LDFLAGS to KBUILD_LDFLAGS")
