xmake_file is specified per-host, as is normal for it, and is therefore now
specified in config.host.  This is not related to the problem.

The actual problem is different.  The LANG_MAKEFRAGS are currently included
*after* xmake_file is included in the main Makefile.in; accordingly, the
definition  X_ADA_CFLAGS= in ada/Make-lang.in *overrides* the definition
X_ADA_CFLAGS=-mdisable-indexing in config/pa/x-ada.

Suggestions for the correct fix are welcome.  I'm worried that moving the
xmake_file inclusion after the LANG_MAKEFRAGS inclusion will have unforseen
side effects (there are several other xmake_files, mostly more complicated).

Perhaps it's best to put the blank definition of X_ADA_CFLAGS
into the main Makefile.in near the top and take it out of the Make-lang.in ?
