installing libtool libraries in different directories

[Paolo Bonzini]

In my Makefile.am I have code like this:

lib_LTLIBRARIES = libgst-gobject.la
libgst_gobject_la_SOURCES = gst-gobject.c
libgst_gobject_la_LDFLAGS = -version-info 1:0:0 -no-undefined

moduleexec_LTLIBRARIES = gst-glib.la
gst_glib_la_LDFLAGS = -rpath $(moduleexecdir) -release $(VERSION) \
        -module -no-undefined
gst_glib_la_LIBADD = libgst-gobject.la
gst_glib_la_DEPENDENCIES = libgst-gobject.la
dist_gst_glib_la_SOURCES = gst-glib.c

However, when I install the package with -j4, this rule starts both 
install targets in parallel:

install-exec-am: install-libLTLIBRARIES install-moduleexecLTLIBRARIES

As a result, the gst-glib library is installed before libgst-gobject has 
been relinked. :(  I'm not sure if it is an Automake or Libtool bug, and 
I can work around it with a rule like this:

install-libLTLIBRARIES: | install-moduleexecLTLIBRARIES

or with a .NOTPARALLEL (the directory is small).  But the bug can be 
more tricky for packages with a non-recursive Makefile...
