Things work much better with release 6.6 and not setting 
solib-absolute-prefix.

There is still a 'Cannot access memory at address 0x0' before reaching 
main().
Stepping works find in main().
Program runs much longer now, but stops at SIG32.

Console stuff:
=========
Cannot access memory at address 0x0
Cannot access memory at address 0x0
info program
Debugging a target over a serial line.
Program stopped at 0x40077228.
It stopped with signal SIG32, Real-time event 32.
Type "info stack" or "info registers" for more information.
info stack
#0  0x40077228 in ?? () from /lib/libpthread.so.0

After issued 'signal SIG32' for continuing things seems to be not right, can 
it be the
access at adress 0x0 or that the libpthread dosen't have any debug-info?
