The libgloss port has been reaching back into newlib internals for a single header whose contents have been frozen for almost a decade. To break this backwards libgloss->newlib dependency, move the acle header to the srcroot include/ so everyone can use the same copy.topic/musl-regex

/* ACLE standardises a set of pre-defines that describe the ARM architecture.
|
|||
These were mostly implemented in GCC around GCC-4.8; older versions |
|||
have no, or only partial support. To provide a level of backwards |
|||
compatibility we try to work out what the definitions should be, given |
|||
the older pre-defines that GCC did produce. This isn't complete, but |
|||
it should be enough for use by routines that depend on this header. */ |
