[PATCH] Remove libada-mk

[Paolo Bonzini]

This patch removes libada-mk and, in addition, the dependency of 
libada/gnattools on the configuration files from the gcc directory. 
This in turn fixes a failure on m68k with the upcoming multilibbing of 
libada.

The values passed currently by libada are:

- exeext: this can be found at configure time for gnattools, and is 
unused for libada.  It is a legacy of when libada also built the tools.

- host_cc_for_libada: Likewise.

- gcc_tmake_file: Used for TARGET_LIBGCC2_FLAGS; also causes the failure 
on m68k.  We can use libgcc.mvars to pass this, which is an 
already-existing mechanism to pass configuration information between gcc 
and target libraries.

- gcc_xmake_file: Unused after my patch to move PA-specific Ada flags to 
the toplevel, committed earlier today.

- warn_cflags: Easily computed at configure time in both libada and 
gnattools.

- nocommon_flag: Set by --enable-checking to catch forgotten "extern" 
for variable declarations in header files.  Not a big deal: it's easier 
to find them with something like

	grep '^[^et  }][^(]*;' *.h

("e" is for enum and extern, "t" is for typedef).  Also, there are 30 
variable declarations in Ada header files compared to 1384 in the gcc 
source code (not counting front-ends other than the C front-end).

Bootstrapped/regtested i686-pc-linux-gnu, C and Ada.  Will commit in 
24/48 hours unless I hear complaints.
