results with TinyCC/x86

[Bruno Haible]

On a x86_64 glibc system, building a Gnulib testdir with tcc (configured to
produce x86 code: './configure --cpu=x86 --triplet=i386-linux-gnu') gives
a number of test failures:

The standard I/O functions appear to be severely broken in this configuration.
(My guess is that tcc does not support the symbol versioning used by glibc.)
