The problem is that make-3.82 broke many things that had been working with
older make versions. For example, make-3.82 broke the linux kernel, gcc,
glibc, and many other major packages.

Heck, if they wanted to break the API, they should have named it make-4.0.
3.82 pretty much sounds like "release accumulated set of bug fixes after
the many year previous version was released" thingy, rather than a major
version which would have been allowed to break existing stuff.

Even Debian has not yet migrated to make-3.82 (only experimental has it,
not even sid).

For crosstool-NG, I only use documented features of make, and it was working
and is still working perfectly with make-3.81. So _I_ consider that the
regresions are in make-3.82.

I think that the key point is that make-3.81 did sort the result of
$(wildcard ...) while make-3.82 does not.

I added a bit of debug stuff into config/config.mk@66:
    $(info ARCHS  ='$(ARCHS)')
    $(info KERNELS='$(KERNELS)')
    $(info CCS    ='$(CCS)')
    $(info LIBCS  ='$(LIBCS)')
    $(info DEBUGS ='$(DEBUGS)')

And here is what make-3.81 on Debian squeeze gives as a result:
    ARCHS  ='alpha arm avr32 blackfin m68k mips powerpc s390 sh sparc x86'
    KERNELS='bare-metal linux mingw32'
    CCS    ='gcc'
    LIBCS  ='eglibc glibc mingw newlib none uClibc'
    DEBUGS ='dmalloc duma gdb ltrace strace'

and here's what make-3.82 on openSuSE 12.1 gives as a result:
    ARCHS  ='arm x86 sh avr32 mips sparc powerpc s390 m68k alpha blackfin'
    KERNELS='mingw32 bare-metal linux'
    CCS    ='gcc'
    LIBCS  ='none mingw eglibc newlib uClibc glibc'
    DEBUGS ='ltrace gdb duma dmalloc strace'

Maybe we could try sorting the output and see if it /fixes/ the issue?

So, if someone comes with a patch that:
  - fixes building crosstool-NG with make-3.82
  - does not break building with make-3.81
  - if not too ugly
I will be glad to apply it. ;-)
