I've updated bintuils to the latest CVS version and applied the patch (I removed
the assert before the debug output though ;)
The output is:
found bad section .eh_frame (index 14) in obj/release/pcre_compile.o
section type=0 section flag=0
/usr/bin/ld: internal error in scan_sections_for_stubs, at arm.cc:5664
collect2: ld returned 1 exit status
make[1]: *** [../../lib/libQtScript.so.4.6.1] Error 1
make[1]: Leaving directory `/mnt/swap/kde/kde-qt/src/script'
make: *** [sub-script-make_default-ordered] Error 2

As the error might be related to Thumb-2 code it might be of interest that
rgular expressions and JavaScript are just-in-time compiled in WebKit, and the
JIT compiler seems to use Thumb(-2) via stubs written in Assembly, unlike the
regularly compiled rest.
