Backported for VSD 3.4

not mentioned in the test for v3.1.26, and checksums are no important part of the software

Done for gpg4win 5 and backported for VSD 3.4 (provided that the gpg4win-4-branch will be used for VSD 3.4).

I tested Ubuntu's version of GCC-15 (powerpc64le cross-compiler) and did not see this build failure:

tested with Gpg4win-5.0.0-beta345:

I figured out that .machine "any" is needed with GCC 15.

I wonder about GCC 15 preparation for the release. If it's good to have, three patches are needed to apply:

• Cherry-picking rCd5fb7cd9b351: Mark nonstring use cases with __nonstring__ attribute.
  • strictly speaking, this adds a macro, which is considered an API change
• Cherry-picking rCf06e90f4137a: cipher:ecc: Silence GCC 15 warning.
• Apply changes of T7721: libgcrypt build-error with gcc-15 on powerpc and alpha

I figured out that .machine "any" is needed with GCC 15.

For Alpha (hppa, and sparc), IIUC, following patch may help:
