Bug#1143972: gcc-13: Checking ALIHASH fails, prevents Ada bootstrap on alpha

Source: gcc-13
Version: 13.4.0-11
Severity: normal

Hello,

on alpha, the gcc-13 build fails because the gnat compiler in the archive
is broken. When using an older version of gcc-13 with a working gnat version,
the build succeeds but fails when checking ALIHASH:

echo "checking ALIHASH ..."; \
p=gnat-13-alpha-linux-gnu; \
old=$(apt-cache show $p | awk '/^Provides/ {print $2}'); \
new=gnat-13-$(debian/ada/libgnat_alihash | sed 's/.*=//'); \
if [ $old = $new ]; then \
  echo "  -> matching alihash ($old)"; \
else \
  echo "  -> alihash mismatch: $old (installed), $new (built)"; \
  if [ xyes = xyes ]; then \
    exit 1; \
  fi; \
fi
checking ALIHASH ...
/bin/bash: line 5: [: too many arguments
  -> alihash mismatch: gnat-13-119f978a
gnat-13-97e8392b (installed), gnat-13-119f978a (built)
make[1]: *** [debian/rules2:1400: stamps/05-build-stamp] Error 1
make[1]: Leaving directory '/home/glaubitz/gcc-13-new/gcc-13-13.4.0'
make: *** [debian/rules:53: build-arch] Error 2

I have no idea what that hash value exactly means, but the bash syntax error
during the check looks suspicious, so I decided to report a bug.

FWIW, the build fully succeeds when disabling the check. I used this, to build
gcc-13_13.4.0-11 for alpha and then tried a fresh local build where again the
ALIHASH check failed.
