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.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
