In this version I added a memcmp() implementation. In v1 I tried with
__builtin_memcmp() but CI failed with clang [1] and gcc 4.8.5.

v2:
- added patch 1 to provide a memcmp() implementation
- made 'rsdp_signature' static const [Phil]
- uses memcmp() instead of __builtin_memcmp()
- added pvh.bin binary with the changes applied

v1: https://lists.gnu.org/archive/html/qemu-devel/2021-03/msg07425.html

Thanks,
Stefano
