Actually libgcrypt’s ‘configure’ reports this above:

--8<---------------cut here---------------start------------->8---
configure: WARNING:
***
*** The config script 
/nix/store/j47ldsz3p5mc3k5yp00lx1jwkan88k53-libgpg-error-1.12/bin/gpg-error-config
 was
*** built for x86_64-unknown-linux-gnu and thus may not match the
*** used host mips64el-unknown-linux-gnu.
*** You may want to use the configure option --with-gpg-error-prefix
*** to specify a matching config script.
***
--8<---------------cut here---------------end--------------->8---

So CROSS_LIBRARY_PATH and LIBRARY_PATH are correct (no confusion between
target and native libraries).  However ‘configure’ uses the
‘gpg-error-config’ tool to determine the library’s location, and it gets
the run that of the native libgpg-error (because the target libgpg-error
isn’t in $PATH), which returns the location of the native libgpg-error.

So indeed, --with-gpg-error-prefix is needed.

Could you send the patch with just a comment above explaining that?

Thanks, and sorry for taking so long!
