This patch works around a rare parallel build race condition using
the force option when soft linking.
The error seen is:
ln: failed to create symbolic link 'libssl.so': File exists
make[4]: *** [Makefile.shared:171: link_a.gnu] Error 1
make[4]: Leaving directory
'/.../build/tmp-glibc/work/x86_64-linux/openssl-native/1.0.2k-r0/openssl-1.0.2k'
Just add the -f flag to the platform independent soft link code to
avoid the collision. This is reasonable since this Makefile removes
the link target before creating a new soft link. The Makefile was
written this way to support platforms that don't allow forcing a
softlink to overwrite an existing link. Only builds on Linux are
supported so that's not a requirement for oe-core recipes.
The openssl team is rewriting their build files so it's not appropriate
for openssl upstream and fixing the root cause of the race condition
was also not pursued.
