avr32 only provides __NR_pread and not __NR_pread64, so the fallback handling must be used. Patch sent upstream: http://lists.uclibc.org/pipermail/uclibc/2013-October/047967.html Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

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.
