setuptoools.bbclass: Do not use -pie with hardening
Fix build when PIE is turned on. It tries to build .so file using -pie and -shared flags together because its doing compile and link in same step CFLAGS and LDFLAGS are combined and does not work, ending in errors e.g. | /mnt/a/oe/build/tmp/work/cortexa7t2hf-neon-vfpv4-bec-linux-musleabi/python-pygpgme/0.3-r0/recipe-sysroot/usr/l ib/Scrt1.o: In function `_start_c': | /usr/src/debug/musl/1.1.16+gitAUTOINC+179766aa2e-r0/git/crt/crt1.c:17: undefined reference to `main' | collect2: error: ld returned 1 exit status This error while cryptic is due to the fact that we are building a shared library but also pass -pie flag to the link step after specify LDHSARED ( which is -shared linker flags ) we can not use -pie when doing shared libs. This is true for all the python modules inheriting setup tools Disable the pie flags thusly for all modules using setuptools since this setting is done in setuptools makefiles which are then used during module compiles (From OE-Core rev: dc1c16e9df365871b2c40998f63f304ffa610447) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
