Problem building ports after upgrade

[Wolfgang Zenker]

Hi,

after upgrading 10-STABLE to r267142 and going to r356862 in ports,
I now have a problem building ports: The ports that I have tried to
build so far failed after the configuration build with

env: NO_PIE: No such file or directory

e.g. nasm:
# portmaster nasm
....
config.status: creating doc/Makefile
config.status: creating config.h
config.status: executing default-1 commands
===>  Building for nasm-2.10.09_1,1
env: NO_PIE: No such file or directory
===> Compilation failed unexpectedly.
Try to set MAKE_JOBS_UNSAFE=yes and rebuild before reporting the failure to
the maintainer.
*** Error code 1

Stop.
make: stopped in /usr/ports/devel/nasm

Any hints where I should start to look?
