Known issues and workarounds with developer tools

[dkonigsberg]

Every toolchain has its share of bugs, gotchas, and workarounds. When we run into them, many of us either figure them out, or furiously search forums/blogs until we find solutions. Some are covered in the official documentation, some aren't, and some are just too obscure. We need a FAQ-like section where we can collect some of this information, mined from forums if necessary, allowing for running commentary on what works or doesn't work for people.
