Generate compiler compatible assembly symbols

Browse Source 
Typically when compiling a function `foo`,  GCC will add a prefix `_` to the symbol, i.e., generate `_foo`. But on some platforms, the compiler will not add prefix. option `ENABLE_ASM_UNDERSCORE_PREFIX` change the default name of global symbols in assembly code.
