-fpic (and -fpie) set a machine specific maximum size of the global
offset table. For SPARC, the limit is 8K, which is usually not enough.
-fPIC (and -fPIE) doesn't set a limit on the size of the global offset
table, which should work for all architectures/code.

There may be slight performance or binary size implications in using
-fPIC/fPIE, but I'll defer to Jakub (or someone more knowledgable than
me in the ways of gcc) to say whether that is the case or not.
