 That seems to be needlessly complex. If LO really can't build correctly 
with --as-needed and there are no intentions to fix that, it should be enough 
to just add --no-as-needed in the right place(s) to LDFLAGS, unconditionally 
(assuming the compiler/linker know this option, of course).

 That said, there are a number of distributions building that way (it's the 
default in openSUSE build service too AFAIK), so while 'everybody does that' 
is not an argument on its own, perhaps we should consider the possibility 
that it is not the toolchain that is broken.
