After a generic configure, make -j 8 bootstrap fails with

>How-To-Repeat:
see above
>Fix:
Maybe the makefile should be modified to have the headers
depend on the thread_builddir:

${thread_builddir}/gthr.h: ${thread_builddir}
        sed -e '/^#/s/\(${uppercase}${uppercase}*\)/_GLIBCPP_\1/g' \
            -e 's,^#include "\(.*\)",#include <bits/\1>,g' \
            < ${toplevel_srcdir}/gcc/gthr.h > $@

${thread_builddir}/gthr-single.h:${thread_builddir}
        sed -e 's/\(UNUSED\)/_GLIBCPP_\1/g' \
            -e 's/\(GCC${uppercase}*_H\)/_GLIBCPP_\1/g' \
            < ${toplevel_srcdir}/gcc/gthr-single.h > $@
