patchlet for linux/fs.h

[Richard Henderson]

Previously this was going unnoticed becuase abs resolved to __builtin_abs.
Recent versions of gcc do not fail to emit the "no declaration" warning
with builtins, which brings it to my attention.

The use of abs is incorrect because the definition is `int abs(int)',
which does not do what you want with loff_t.
