We inherit gcc from the yocto base, and while there is nothing that
prohibits us from fixin particular bugs in that I don't want to just
change to a massively different version, because that could expose
issues (build and runtime) in other parts of the runtime. I want to use
the same version that upstream yocto tested against.

However, I know there is one arm specific thing in our compilers that
is a bit different from what is common. It does not enable "thumb" mode
by default. That causes some issues with GtkWebkit i believe. You can
try adding -mthumb to CPPFLAGS and see if this affects anything.
