GMP 5.0.5 build fails with tcc due to x86_64 asm (unknown register...)

[bodrato at mail.dm.unipi.it]

This discussion begun on gmp-bugs, was moved to gmp-discuss... I reply to
gmp-devel to avoid confusions for the users, because the problem I've
found arise with the current head repository only.

In the development version (from the repo) I tried:

$ CC=tcc ./configure --disable-assembly
...
configure: summary of build options:

  Version:           GNU MP 5.0.90
  Host type:         x86_64-unknown-linux-gnu
  ABI:               64
  Install prefix:    /usr/local
  Compiler:          tcc
  Static libraries:  yes
  Shared libraries:  yes
$ make
...
$ make check
...
/bin/bash ../libtool --mode=compile --tag=CC ../mpn/m4-ccas --m4="m4" tcc
-c -DHAVE_CONFIG_H -I. -I.. -I..    -DNO_ASM  `test -f 'amd64call.asm' ||
echo './'`amd64call.asm
libtool: compile:  ../mpn/m4-ccas --m4=m4 tcc -c -DHAVE_CONFIG_H -I. -I..
-I.. -DNO_ASM amd64call.asm  -DPIC -o .libs/amd64call.o
m4  -DHAVE_CONFIG_H -DNO_ASM -DPIC amd64call.asm >tmp-amd64call.s
 tcc -c -DHAVE_CONFIG_H -I. -I.. -I.. -DNO_ASM tmp-amd64call.s -DPIC -o
.libs/amd64call.o
tmp-amd64call.s:120: error: unknown opcode 'movq'
...

Even with the "--disable-assembly" option given to configure, "make check"
is asking to the compiler to assemble a .s file. It didn't happen with the
"--host=none" option given to GMP-5.0 .
If you have some suggestion about how to fix this, I'll be happy to try!

Best regards,
