PATCH: System error names, again.

PATCH: System error names, again.

[Peter Stephenson]

The generation of names for system errors is broken on Linux again.
We restrict the list of files which may contain error
number definitions to the longest list yet found.  This means
asm-generic/errno-base.h doesn't get included.

I don't think that test is necessary, but have a careful look to see if
this is broken on any system (Src/Modules/errnames.c; you may have to
remove it to regenerate it).
