bug#63864: cryptsetup-static-2.3.7 can't find gcrypt

[Faré]

I'm trying to cross-compile Guix for my pinephone pro (arm64) from a
x86-64 laptop, as per https://git.sr.ht/~abcdw/guix-pinephonepro, but
when I try to add support for encrypted filesystems, guix fails to
build cryptsetup-static-2.3.7, with the following error in its
configure script:

checking for linux/if_alg.h... yes
checking for libgcrypt-config... no
checking for LIBGCRYPT - version >= 1.6.1... no
checking for libgcrypt-config... (cached) no
checking for LIBGCRYPT - version >= 1.1.42... no
configure: error: You need the gcrypt library.
error: in phase 'configure': uncaught exception:

I'll attach the channels-lock.scm and the full error log. The code is
otherwise in https://git.sr.ht/~abcdw/guix-pinephonepro modulo trying
to add cryptsetup support via a mapped-device of (type
luks-device-mapping).

“The individual has always had to struggle to keep from being overwhelmed by
the tribe. To be your own man is a hard business. If you try it, you’ll be
lonely often, and sometimes frightened. But no price is too high to pay for
the privilege of owning yourself.”  — Rudyard Kipling
