No, that's not possible in a clean way.

In this situation, I believe the best option is:

 (1) As a temporary measure, take the src/libgcrypt.m4 file from the
 libgcrypt sources, and create a patch that adds it to the m4/
 directory of systemd sources. This way, regardless of whether
 libgcrypt is available or not, the AM_PATH_LIBGCRYPT m4 macro will be
 available for autoreconf to use.

 (2) As a permanent measure, upstream the other systemd patches so that
 ultimately we can get rid of the SYSTEMD_AUTORECONF = YES.

Best regards,

Thomas
