Improve reproducible build of:
openssl-staticdev
openssl-dbg
libcrypto
There are two main causes that prevent reproducible build, both related to
the generated file "buildinf.h":
1. "buildinf.h" contains build host CFLAGS, containing various build
host references. We need to pass sanitized CFLAGS to the script
generating this file ("mkbuildinf.pl". )
2. We also need to modify the script "mkbuildinf.pl" itsel in order to
generate a build timestamp based on SOURCE_DATE_EPOCH, if present in
the environment.

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.
