I don't think so.  IIRC, HP-UX's linker distinguishes data symbols
from code symbols.

There might be a macro able to do what you want.  The problem is that
you'd have to supply the right type for the variable, and any headers
required to declare the types (and maybe the variable itself), so it's
not too much different from using AC_TRY_LINK directly.
