So, I'm trying to build the most recent Chromium port in order to attempt
debugging some issues that I'm seeing, and I'm currently getting a few
build failures:
[179/16428] python

Working around it for the sake of the build by removing the extern on environ
(even though I'm almost entirely certian that it won't work correctly in the
final version, I get the missing '-lexecinfo' that I initially ran into
in bug 214450:
obj/third_party/WebKit/Source/wtf/wtf/Assertions.o: In function
`WTFGetBacktrace(void**, int*)':
./out/Debug/../../third_party/WebKit/Source/wtf/Assertions.cpp:167:
undefined reference to `backtrace'
clang-3.9: error: linker command failed with exit code 1 (use -v to see
invocation)
I'm runnign on
$ uname -a
FreeBSD oneeye 11.0-RELEASE-p1 FreeBSD 11.0-RELEASE-p1 #0 r306420: Thu

Is there anything obvious I'm missing? For the environ, it seems like we may
be running into the same issue as this:
https://git.merproject.org/mer-core/qtbase/commit/ccf74b592809e0c5a613eff27d6431a4c659e368
Buy I don't see anything in either linker flags or the wrapper scripts that
would lead to -Wl,-no-undefined getting passed down here. Does lld behave
differently than gnu ld? I noticed that we seem to be using it now, no idea
how new that is.
I've definitely built older versions successfully.
