Since commit efc6c070aca ("configure: Add a test for the minimum
compiler version") the minimum compiler version required for GCC
is 4.8, which supports __builtin_bswap().
Remove the NetBSD specific ifdef'ry.
This reverts commit 1360677cfe3ca8f945fa1de77823df21a77e4500
("makes NetBSD use the native bswap functions").
