Missing prototype for default_remapped_builtin() and default_omp_target_decl()

[klpeders]

Build fail because of missing prototype for default_remapped_builtin() and default_omp_target_decl():

g++ -c   -g [...]  -o riscv.o [...] ./build/src/newlib-gcc/gcc/config/riscv/riscv.c
./build/src/newlib-gcc/gcc/config/riscv/riscv.c:4447:470: error: ‘default_remapped_builtin’ was not declared in this scope
./build/src/newlib-gcc/gcc/config/riscv/riscv.c:4447:496: error: ‘default_omp_target_decl’ was not declared in this scope
Makefile:2076: recipe for target 'riscv.o' failed

Maybe add targhooks.h to patch:

I don't manage to reproduce this issue. Could you tell me how you compile the toolchain and using which gcc version ?
