libstdc++ gets configure error in cross builds

[Paul Koning]

Gents,

I'm trying to do a cross-build of gcc 4.5.1.  It works fine until I get to libstdc++v3, where configure blows up with a message saying "Link tests are not allowed after GCC_NO_EXECUTABLES".  This happens on the "checking for shl_load" step (line 11221 in configure).

I looked at configure.ac to see if there were any clues.  I can't tell which line in configure.ac produces the offending line in configure (not enough autoconf skills).  In an earlier gcc (3.3.3) there was a similar issue, and in that case I worked around it by removing "GLIBCPP_CHECK_COMPILER_VERSION" from the configure.in file.  But that line doesn't exist in configure.ac and attempts to find something analogous didn't get me anywhere.

Help...
