These ‘-m’ options are defined for GNU/Linux targets:
-mglibcUse the GNU C library. This is the default except on ‘*-*-linux-*uclibc*’, ‘*-*-linux-*musl*’ and ‘*-*-linux-*android*’ targets.
-muclibcUse uClibc C library. This is the default on ‘*-*-linux-*uclibc*’ targets.
-mmuslUse the musl C library. This is the default on ‘*-*-linux-*musl*’ targets.
-mbionicUse Bionic C library. This is the default on ‘*-*-linux-*android*’ targets.
-mandroidCompile code compatible with Android platform. This is the default on ‘*-*-linux-*android*’ targets.
When compiling, this option enables -mbionic, -fPIC, -fno-exceptions and -fno-rtti by default. When linking, this option makes the GCC driver pass Android-specific options to the linker. Finally, this option causes the preprocessor macro __ANDROID__ to be defined.
-tno-android-ccDisable compilation effects of -mandroid, i.e., do not enable -mbionic, -fPIC, -fno-exceptions and -fno-rtti by default.
-tno-android-ldDisable linking effects of -mandroid, i.e., pass standard Linux linking options to the linker.
