[Xen-devel] [PATCH v4] raisin: enable ovmf build for arm64

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

nasm is not a dependency on arm64.
Print out a message that on x86_32 we are building ovmf x86_64.
Add CentOS dependencies to the ovmf component.

---

Changes in v4:
- fix CentOS dependency list
- mention CentOS in the commit message

Changes in v3:
- allow x86_64 build on x86_32
- print out a message that on x86_32 we are building ovmf x86_64
- add a comment on the usage of large model on arm64

Changes in v2:
- disable x86_32 build (it doesn't work, but it wasn't explicitly
  disabled)
- remove export GCC48_AARCH64_PREFIX= as it is not necessary
- add a comment on why we are using -t GCC48
