The more Emscripten diverges from the standard behavior of compiler tool
chains, the harder it is to adapt other build tools to work with it. The
issues I am having with GYP are symptomatic of this.
In the specific case of "-s USE_SDL=2" vs the standard "-lSDL2", if the
latter is brittle, why isn't -lc brittle for regular C/C++ compilers?
There is a well defined search path; directories specified with -L come
before the default directories. In other words, it is not brittle at
all. If you specify a -L that contains a library with the same name as a
system library, you are expected to know what you are doing.
Emscripten should likewise search any specified -L directories and, if a
specified library isn't found, then it should search its built-in
libraries and equivalent functions and then the ports.
It should also not issue errors that a library specified with -l can't
be found, if that libraries functionality is built into Emscripten. E.g.
specifying -lGLESv2 should not cause emlink to spit out "Error:
libGLESv2.a: File not Found" (or something like that) as the GLESv2
functions are all included in Emscripten.
This changes would make Emscripten much more friendly to other build tools.
