Someone mentioned to me that he's getting SIGBUSes in grotty.  The root
cause of this is that the variable `usual' in libc/stdio/findfp.c does
not always have 8-byte alignment, which it needs because FILE->_offset
is a quad.

One of gcc, gas, or ld would appear to be failing to properly align
.reserve's, and probably .common's as well.
