Bug#330871: boa should check for sendfile() returning ENOSYS

[Anthony Towns]

package boa
tag 330871 + patch
thanks

Hi, I came across this bug too (on mipsel), saw this bug via google,
and tried patching boa to "check for sendfile() returning ENOSYS" --
turned out to be pretty easy, and works fine for me. The patch below just
makes boa do the same thing it would have if configure hadn't enabled
sendfile support when ENOSYS is returned, so seems pretty safe.

HTH.

Cheers,
aj
