Getting at Libs.private from autoconf

[David Evans]

  Hi, all.

  Libs.private is nice but there doesn't seem to b a clean way of
getting at --libs --shared from autoconf.  How about defining
foo_STATICLIBS to do this?  Something like

*** pkg.m4.orig	2009-02-05 13:34:12.000000000 +0000
--- pkg.m4	2009-02-05 14:15:21.000000000 +0000

  AC_ARG_VAR([$1][_LIBS], [linker flags for $1, overriding pkg-config])dnl
  
  pkg_failed=no
  AC_MSG_CHECKING([for $1])
  
  _PKG_CONFIG([$1][_CFLAGS], [cflags], [$2])
  _PKG_CONFIG([$1][_LIBS], [libs], [$2])
  
! m4_define([_PKG_TEXT], [Alternatively, you may set the environment variables $1[]_CFLAGS
! and $1[]_LIBS to avoid the need to call pkg-config.
  See the pkg-config man page for more details.])
  
  if test $pkg_failed = yes; then

Tested on version 0.22.
