I compiled https://github.com/json-c/json-c using the command `sh
autogen.sh && ./configure --host=aarch64 && make`. Unexpectedly this
creates an x64 binary.

The correct argument in my case is --host=aarch64-linux-gnu

I think this should be an error. Currently, there is only the output
"checking for aarch64-gcc... no" but this does not abort. So the error
is postponed until the binary is actually used.

If I give --host=gibberish I do get an error as expected:

"checking host system type... Invalid configuration `gibberish':
machine `gibberish' not recognized"

Thanks for your work GNU people,

Erik van Velzen

compiler lookup is an autoconf macro (AC_PROG_CC).  automake isn't involved.
reassigning to the autoconf project for consideration.

care must be taken to not break the non-cross-compiling case, but that prob=
ably
might mean that trying to improve the UX without breaking existing valid fl=
ows
is impossible without being extremely fragile.  so as much as it sucks, thi=
s is
probably a "sigh, that's just the way it is" situation.

consider a multilib system:
* default ABI is x86_64 (64-bit) but x86 (32-bit) also works
* `gcc` supports both depending on compiler flags
* `./onfigure` will produce 64-bit binaries
* `./onfigure --host=3Dx86_64` will produce 64-bit binaries, but there is no
  `x86_64-gcc` (if any exist, it'd be more like `x86_64-pc-linux-gcc`)
* `./configure --host=3Di686 CFLAGS=3D'-m32'` will produce 32-bit binaries,=
 but
  there is no `i686-gcc`

this is coming from the config project [1].  it is responsible for parsing
the specified tuple to see if it resembles something reasonable.  giving it
gibberish is not reasonable, so it aborts.  but a bare cpu name like you
showed at the top is valid syntax.  it just doesn't expand the way you're
expecting.
