Similarly to commit a73e82ef912, test the libraries link correctly
before considering them as usable.

This fixes using ./configure --static on Ubuntu 18.04:

  $ make subdir-aarch64-softmmu
  [...]
    LINK    aarch64-softmmu/qemu-system-aarch64
  /usr/bin/ld: cannot find -lgfapi
  /usr/bin/ld: cannot find -lglusterfs
  /usr/bin/ld: cannot find -lgfrpc
  /usr/bin/ld: cannot find -lgfxdr
  collect2: error: ld returned 1 exit status
  Makefile:204: recipe for target 'qemu-system-aarch64' failed
  make[1]: *** [qemu-system-aarch64] Error 1

  $ fgrep gf config-host.mak
  GLUSTERFS_LIBS=-lacl -lgfapi -lglusterfs -lgfrpc -lgfxdr -luuid

  $ lsb_release -cri
  Distributor ID: Ubuntu
  Release:        18.04
  Codename:       bionic
