libstdc++-v3/configure contains this:

    ldver=`$LD --version 2>/dev/null | head -1 | \
           sed -e 's/GNU \(go\)\{0,1\}ld \(version \)\{0,1\}\(([^)]*)
\)\{0,1\}\([0-9.][0-9.]*\).*/\4/'`

that sed script fails with /usr/bin/sed on Solaris, disabling symbol
versioning.

Here's an example of what I get:

++ /sbcimp/run/pd/binutils/32-bit/2.18/bin/ld --version
++ head -1
++ sed -e 's/GNU ld \(version \)\{0,1\}\(([^)]*)
\)\{0,1\}\([0-9.][0-9.]*\).*/\3/'
+ ldver='GNU ld (GNU Binutils) 2.18'
++ echo GNU ld '(GNU' 'Binutils)' 2.18
++ nawk -F. '{ if (NF<3) $3=0; print ($1*100+$2)*100+$3 }'
+ glibcxx_gnu_ld_version=1800

This leads to:

configure: WARNING: === Linker version 1800 is too old for 
configure: WARNING: === full symbol versioning support in this release of GCC. 
configure: WARNING: === You would need to upgrade your binutils to version 
configure: WARNING: === 21400 or later and rebuild GCC. 
configure: WARNING: === Symbol versioning will be disabled. 
configure: versioning on shared library symbols is no 

Could be fixed by requiring a POSIX sed, or by using awk to select the version
(we already require POSIX awk)
