[Enrico Scholz]

Although libgcrypt support is optional, its development files are
are always required to expand AM_PATH_LIBGCRYPT.  Build might fails else
with

| libtoolize: copying file `m4/lt~obsolete.m4'
| configure.ac:446: warning: macro 'AM_PATH_LIBGCRYPT' not found in library
| ...
| configure.ac:446: error: possibly undefined macro: AM_PATH_LIBGCRYPT
| autoreconf: .../autoconf failed with exit status: 1
| + bbfatal 'autoreconf execution failed.'
| + echo 'ERROR: autoreconf execution failed.'
