[parisc-linux] Problem with weak symbols

Don't use asm's to weaken symbols.  Use GCC's attribute weak.  GCC
needs to know whether a symbol is weak or not.

What is printed in the first case is the value of the $dp register.
For some reason, $global$ is not being subtracted from the symbol value
(zero).  This is a linker bug, not a gcc bug.

We probably should be using DPREL relocations for linux_foo.
