Subject: Makefile cleanups for webstead
X-Git-Tag: bedstead-3.261~50
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~bjharris/git?a=commitdiff_plain;h=0e23fc66583d6372cc54e00b297408b8adcf71a2;p=bedstead.git

Makefile cleanups for webstead

Add -sINCOMING_MODULE_JS_API because in newer Emscripten -sSTRICT
empties it.  Remove -sMODULARIZE because -sEXPORT_ES6 implies it.  Add
-O2 since the compiled code will probably be run more than once.  Pass
standard compiler flags to emcc.  Build bedstead.js in all-web, and
remove it in clean.
