The openssl build system generates buildinf.h containing the full compiler command line used to compile objects. This breaks reproducibility, as the compile command is baked into libcrypto, where it is used when running `openssl version -f`. Add stripped build variables for the compiler and cflags lines, and use those when generating buildinfo.h. This is based on a similar patch for older openssl versions: https://patchwork.openembedded.org/patch/147229/ (From OE-Core rev: cbc9b743a711f07c04cf9f5b2fc3f83da6d28913) Signed-off-by: Martin Hundebøll <martin@geanix.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
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.
