libgcc: xtensa: use built-in configuration
Now that gcc provides __XCHAL_* definitions use them instead of XCHAL_*
definitions from the include/xtensa-config.h. That makes libgcc
dynamically configurable for the target xtensa core.
libgcc/
* config/xtensa/crti.S (xtensa-config.h): Replace #inlcude with
xtensa-config-builtin.h.
* config/xtensa/crtn.S: Likewise.
* config/xtensa/lib1funcs.S: Likewise.
* config/xtensa/lib2funcs.S: Likewise.
* config/xtensa/xtensa-config-builtin.h: New File.
