9b5167c07b make(1): make ampersand in ${VAR:from=to&} an ordinary character 
In SysV substitutions, wildcards are expressed with % instead of &.  The
& is not mentioned in the manual page, and having another wildcard for
the whole word would be such an obscure feature that not even pkgsrc uses
it.  The easiest way to discover this feature had been to read the source
code of make(1) or to use a fuzzer and accidentally stumble upon this
edge case.

Until today there was no corresponding unit test though.

There are just too many variables called "flags" in this file, and their
constants must not accidentally overlap.

6bd27cf6bd for Xen MSI, fallback to INTx when PHYSDEVOP_map_pirq fails for the device 
apparently Xen requires VT-d to be enabled in BIOS for PHYSDEVOP_map_pirq
to work, this change makes it work on systems with VT-d disabled or missing

Renaming these flags makes it obvious that VarPattern is used in a few
places where it doesn't belong.  These will be fixed in follow-up
commits.

2b74fdb213 make(1): rename Varf_Flags to VarEvalFlags 
In var.c there are lots of different flag types.  To make any accidental
mixture obvious, each flag group gets its own prefix.

The only flag group that is visible outside of var.c is concerned with
evaluating variables, therefore the "e", which replaces the former "f"
that probably just meant "flag".
