Why not put the whole build tree on the ram disk?
I might be spoiled there.

Not really.

You could probably cope without, with something like

# AC_SUBST(ramdisk) adequately from configure.
libfoo_la_LIBADD = $(ramdisk)/libconv1.la $(ramdisk)/libconv2.la ...

# Could use EXTRA_..._DEPENDENCIES with Automake 1.12.
libfoo_la_DEPENDENCIES = $(libfoo_la_LIBADD)
$(ramdisk)/libconv1.la: sub/libconv1.la
        cp -p sub/libconv1.la $@
$(ramdisk)/libconv2.la: ...
...

Cheers,
Ralf
