clang was spewing warnings about the unrecognized -fno-default-inline. (Oddly,
it warns only with -c, not when compiling directly to an executable.) For
completeness we also check -pipe, even though clang is OK with that one.
It should be fine to omit either flag. gcc -fno-default-inline drops the
implicit 'inline' annotation on functions defined inside a class scope, but
'inline' is only a hint anyway. -fno-default-inline does not change linkage.
-pipe is merely a compile speed optimization.
This turns off -Werror by default except in the Debian package.
-Werror is inherently unportable and breaks things on OS X. While it
can cause problems in Debian too, this is at least a little better.
It also turns off -pedantic in src/protobufs, because apparently
protoc output doesn’t compile with -pedantic on all platforms.
