Same here, it would probably help for Android / iOS (even though I think they would probably still require patching luaconf.h).
I've built and used liblua 5.3.4 with success on Android and iOS. For iOS I patched the os_system function, as system() isn't available on iOS.
And made some changes in the Makefile. I didn't need to change luaconf.h
That's a bit out of the topic but I build for both platforms.
For system, I do this in luaconf.h to avoid patching the rest of the sources:
+#if defined(__APPLE__)
+#include <TargetConditionals.h>
+#if defined(TARGET_IPHONE_SIMULATOR) || defined(TARGET_OS_IPHONE)
+#define LUA_USE_IOS
+#endif
+#endif
+/* iOS does not have system() (Seriously, Apple...) */
+#ifdef LUA_USE_IOS
+#include <stdlib.h>
+#undef system
+#define system(command) ({ command ? -1 : 0; })
+#endif
Regarding Android, I have a patch related to LOCALE:
+#if defined(LUA_USE_ANDROID) && !defined(lua_getlocaledecpoint)
+#define lua_getlocaledecpoint() ('.')
+#endif
... and I have a patch in lmathlib.c to avoid using log2().
I have a few other patches for Windows / MinGW. I should Open Source that fork...
