The Debian 7 (Wheezy) members of the buildfarm (lapwing, skate, snapper)
are all getting past the gssapi_ext.h check you added and then failing
like this:

ccache gcc -std=gnu99 -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Werror=vla -Wendif-labels -Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -fexcess-precision=standard -g -O2 -Werror -I../../../src/include -DENFORCE_REGRESSION_TEST_NAME_RESTRICTIONS -D_GNU_SOURCE -I/usr/include/libxml2 -I/usr/include/et -c -o be-gssapi-common.o be-gssapi-common.c
be-gssapi-common.c: In function 'pg_store_delegated_credential':
be-gssapi-common.c:110:2: error: unknown type name 'gss_key_value_element_desc'
be-gssapi-common.c:111:2: error: unknown type name 'gss_key_value_set_desc'
be-gssapi-common.c:113:4: error: request for member 'key' in something not a structure or union
be-gssapi-common.c:114:4: error: request for member 'value' in something not a structure or union
be-gssapi-common.c:115:7: error: request for member 'count' in something not a structure or union

be-gssapi-common.c:119:2: error: implicit declaration of function 'gss_store_cred_into' [-Werror=implicit-function-declaration]

Debian 7 has been EOL five years or so, so I don't mind saying "get a
newer OS or disable gssapi". However, is it worth adding another
configure check to fail a little faster with whatever Kerberos
version this is? Checking that gss_store_cred_into() exists
seems like the most obvious one of these things to test for.
