distutils-base.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
