That's how I do it at the moment, but I want to convert to a non-recursive

Agreed.  That is definitely a better solution, I like it a lot :-)

Actually, now that you point it out, I would hit that problem myself, since m4
has normal _LTLIBRARIES, noinst_LTLIBRARIES and modules.  I would be happy if
I could do this:

~    AM_LDFLAGS = everything gets these
~    noinst_LTLIBRARIES_LDFLAGS = these are for convenience libs
~    lib_LTLIBRARIES_LDFLAGS = these are for other libtool libs
~    libm4_la_LDFLAGS = but I can override non module libs individually

That is, I think target specific flags should override PRIMARY group flags,
not be in addition to them.

Cheers,
        Gary.
