run command 'time bitbake webkit-gtk -c compile' on the host which failed:

without patch till compile fails:
real 49m2.496s
user 102m47.789s
sys 31m18.698s

with the patch:
real 44m9.000s
user 106m45.182s
sys 30m53.223s


On the host build doesn't fail:

Without patch:
real 76m1.646s
user 86m36.704s
sys 38m39.103s

With patch:
real 63m36.193s
user 86m9.274s
sys 37m48.431s

It seems the link option doesn't increase the compile time.

Kai
