[Buildroot] [PATCH] libgcrypt: install libgcrypt-config in host directory

[Arnout Vandecappelle (Essensium/Mind)]

Packages depending on libgcrypt call libgcrypt-config to determine its
CFLAGS.  If libgcrypt-config happens to be installed on the host, this
will add /usr/include to the target include path.  So make sure
libgcrypt-config is in the host directory.
