Subject: [PATCH] Allow building libgcrypt without Brainpool curves
* README: Document possibility to build without brainpool curves
* cipher/ecc-curves.c: Conditionalize brainpool curves definitions
* configure.ac: Implement possibility to build without brainpool curves
* tests/curves.c: Skip brainpool curves if they are not built-in
* tests/keygrip.c: Skip brainpool curves if they are not built-in
