fix position independent loads of function symbols.

For `extern int x[1];`, can use PCREL32 for &x. But for `extern int
x(int)`, must use GOTREL, when not being called directly (that's PLT).
Therefore the type of an external symbol (actually just whether it
denotes a function) matters when deciding what kind of relocation to
emit, so keep that information.
