uClibc: 0.9.33.2: Unbreak on avr32 after recent pread patches

Subject: [PATCH-0.9.33] common/pread_write.c: unbreak on archs without __NR_pread64

Some archs (avr32 in particular) still doesn't define __NR_pread64, so

we should fall back to __NR_pread if it isn't available.

The code nicely checks for it, but then ends up hard coding the syscall

to use __NR_pread64 afterwards, rendering the check useless. Fix it by

using the result of the test instead.
