Log Message:
A few chanes rolled into one:
 * Use GYP_DEFINES instead of patching the .gyp file to use the
   pkgsrc-provided icu package
 * Disable the verbose build, but leave it commented out
 * On NetBSD/i386, build with -mstackrealign -mpreferred-stack-boundary=4
 * Modify how the tests are invoked, and adapt after a "native" build
 * Use the newly created chromium-depot_tools package to make the tests run
 * Fix the platform/semaphore.cc fix for NetBSD > 6.99.4, include \ 
<sys/param.h>
 * Unlimit the data size to make more tests succeed
PKGREVISION bumped.
 
With this, out of 6652 tests expected to pass, 24 fail and 1 crash,
down from initially 33 / 1.
