Ada: Replace hardcoded GNAT commands for GNAT tools
This replaces the hardcoded gnat{make,link,bind,ls} commands with expansion
of the GNAT{MAKE,BIND} variables computed by the configure machinery, during
the build of the GNAT tools.
The default GNATMAKE_FOR_HOST duplicates the default GNATMAKE, and someone
setting GNATMAKE in the toplevel configuration may want it applied for all
host compilations. Direct assignment of GNATMAKE_FOR_HOST keeps working.
gcc/ada/
PR ada/120106
* gcc-interface/Make-lang.in: Set GNAT{MAKE,BIND,LINK_LS}_FOR_HOST
from GNAT{MAKE,BIND} instead of using hardcoded commands.
gnattools/
PR ada/120106
* configure.ac: Remove ACX_NONCANONICAL_HOST and add ACX_PROG_GNAT.
* configure: Regenerate.
* Makefile.in: Do not substitute host_noncanonical but substitute
GNATMAKE and GNATBIND.
Set GNAT{MAKE,BIND,LINK_LS}_FOR_HOST from GNAT{MAKE,BIND} instead
of using hardcoded commands.
