This will be used by fuse(4).

939e5de8d4 Fix rookie mistake - it's nitems(), not sizeof().

1a8577fa68 Add defines for Linux errno values and use them to make linux_errtbl[] 
more readable.  While here, add linux_check_errtbl() function to make
sure we don't leave holes.

Also introduce a static assert to ensure the list is kept up to date.

6e481f83f7 Share a single bsd-linux errno table across MD consumers 
Three copies of the linuxulator linux_sysvec.c contained identical
BSD to Linux errno translation tables, and future work to support other
architectures will also use the same table.  Move the table to a common
file to be used by all.  Make it 'const int' to place it in .rodata.

(Some existing Linux architectures use MD errno values, but x86 and Arm
share the generic set.)

This change should introduce no functional change; a followup will add
missing errno values.
