Ok, we have to questions here:
a- should we support other SEARCH_PATHS in linker scripts
b- should we use a diffrente LIBS variable for target-softmmu and *-user

I think that we definitely want "a".  I tend to think that using the
same libraries for all binaries is a good idea, but I think we shouldn't
confuse the isues.

Please comment in my series to use the default SEARCH_PATH of the linker
on the linker script.

Otherwise, is there any reason to have that different SEARCH_PATH?

Later, Juan.
