Mingli Yu d3886294db nfs-utils: fix build error under tests folder
* Redefine the reference path of libnfs.a to
  ../support/nfs/.libs/libnfs.a to fix below
  error when run "make -C tests statdb_dump".
  | make: *** No rule to make target '../support/nfs/libnfs.a', needed by 'statdb_dump'.  Stop.
  | make: *** No rule to make target '../../support/nfs/libnfs.a', needed by 'nsm_client'.  Stop.

* The function generic_make_pathname is introduced in
  nfs-utils 2.3.1.
  Add the source file which defines function generic_make_pathname to
  libnsm_a_SOURCES of libnsm.a to fix the undefined reference
  when run "make -C tests statdb_dump"
  | ../support/nsm/libnsm.a(file.o): In function `nsm_make_pathname':
  | /usr/src/debug/nfs-utils/2.3.1-r0/nfs-utils-2.3.1/support/nsm/file.c:175: undefined reference to `generic_make_pathname'
  | /usr/src/debug/nfs-utils/2.3.1-r0/nfs-utils-2.3.1/support/nsm/file.c:175: undefined reference to `generic_make_pathname'
  | /usr/src/debug/nfs-utils/2.3.1-r0/nfs-utils-2.3.1/support/nsm/file.c:175: undefined reference to `generic_make_pathname'
  | ../support/nsm/libnsm.a(file.o): In function `nsm_setup_pathnames':
  | /usr/src/debug/nfs-utils/2.3.1-r0/nfs-utils-2.3.1/support/nsm/file.c:280: undefined reference to `generic_setup_basedir'
  | collect2: error: ld returned 1 exit status

* After the logic of commit[dbb643e Removed missing-prototypes warnings.]
  introduced, there comes below error when run
  "make -C tests/nsm_client nsm_client"
  | nlm_sm_inter_svc.c:20:1: error: no previous prototype for 'nlm_sm_prog_3' [-Werror=missing-prototypes]

  It is because rpcgen doesn't generate -Wmissing-prototypes
  free code for nlm_sm_inter_svc.c with below logic
  in tests/nsm_client/Makefile.am
  [snip]
  GENFILES_SVC    = nlm_sm_inter_svc.c
  [snip]
  $(GENFILES_SVC): %_svc.c: %.x $(RPCGEN)
        test -f $@ && rm -rf $@ || true
        $(RPCGEN) -m -o $@ $<
 So add the patch to not fatalize -Wmissing-prototypes.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
