Hmm, there is no xdr library required on Linux, so we don't want to
throw an error in case. Its just part of glibc
When trying to compile libvirt on Windows libportablexdr for example
is necessary. On Linux I get this output in config log:
configure:41995: checking for xdrmem_create in -lportablexdr
configure:42030: gcc -o conftest -g -O2 conftest.c -lportablexdr >&5
/usr/bin/ld: cannot find -lportablexdr
collect2: ld returned 1 exit status
[...]
configure:42069: checking for library containing xdrmem_create
configure:42110: gcc -o conftest -g -O2 conftest.c >&5
configure:42117: $? = 0
configure:42148: result: none required
The first explicit check for libportablexdr fails, but the second test
succeeds and finds xdrmem_create from glibc.
