User-agent: KMail/5.1.3 (Linux/4.4.0-203-generic; KDE/5.18.0; x86_64; ; )

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:

FAIL: test-binary-io.sh
FAIL: test-canonicalize
FAIL: test-chown
FAIL: test-closein.sh
FAIL: test-fchownat
FAIL: test-fclose
FAIL: test-fdutimensat

FAIL: test-linkat
FAIL: test-lseek.sh
FAIL: test-lstat
FAIL: test-pread.sh
FAIL: test-pwrite.sh
FAIL: test-read-file
FAIL: test-rename
FAIL: test-renameat
FAIL: test-renameatu
FAIL: test-stat
FAIL: test-statat
FAIL: test-supersede
FAIL: test-truncate
FAIL: test-utime
FAIL: test-utimens
FAIL: test-utimensat
FAIL: test-yesno.sh
FAIL: test-fts

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.)
