xmlstarlet: fix static linking

Make sure we take into account libgpg-error when linking against
libgcrypt, by adding a patch against xmlstarlet configure.ac. The
handling of static libraries is clearly horrible in this configure.ac
script, using pkg-config would be a lot better, but it's also a lot
more work.

+Subject: [PATCH] Fix static linking problem with libgcrypt
+
+When libgcrypt is used, it is linked with libgpg-error, so we should
+also test that libgpg-error is available, and include -lgpg-error in
+the LIBS variable.
+
+This fixes build issues like:
+
+  CCLD     xml
+/home/thomas/projets/buildroot/output/host/usr/bfin-buildroot-uclinux-uclibc/sysroot/usr/lib/libexslt.a(crypto.o): In function `_exsltCryptoGcryptInit':
+crypto.c:(.text+0x112): undefined reference to `_gcry_check_version'
+/home/thomas/projets/buildroot/output/host/usr/bfin-buildroot-uclinux-uclibc/sysroot/usr/lib/libexslt.a(crypto.o): In function `_exsltCryptoRc4DecryptFunction':
+crypto.c:(.text+0x316): undefined reference to `_gcry_cipher_open'
+crypto.c:(.text+0x32a): undefined reference to `_gcry_strerror'
+crypto.c:(.text+0x34c): undefined reference to `_gcry_cipher_setkey'
+
+Which are caused by the AC_SEARCH_LIBS() test for libgcrypt to fail
+due to -lgpg-error not been present in the LIBS variable.
+
+Note that using PKG_CHECK_MODULES() would be a much much better
+replacement than this complicated handling of static libraries, but
+it's a much more significant effort.
