Pseiderer/add nios2 and xtensa 001 (#119)
* double-conversion: enable for nios2
Nios2 supports double conversion, tested using qemu:
./main || echo "correct"
correct

Note:
Double-conversion tested with:
$ cat div.c
double Div_double(double x, double y) { return x / y; }
$ cat main.c
double Div_double(double x, double y);
int main(int argc, char** argv) {
double result = Div_double(89255.0, 1e22);
if (result == 89255e-22) {
printf("correct result %e\n", result);
return 1;
} else {
printf("wrong result %e\n", result);
return 0;
}
}
Tested for xtensa (using qemu_xtensa_lx60_defconfig plus BR2_PACKAGE_HOST_QEMU_LINUX_USER_MODE):
$ ./host/bin/xtensa-buildroot-linux-uclibc-gcc -c div.c
$ ./host/bin/xtensa-buildroot-linux-uclibc-gcc -c main.c
$ ./host/bin/xtensa-buildroot-linux-uclibc-gcc -o main main.o div.o
$ ./host/bin/qemu-xtensa -L staging main
correct result 8.925500e-18

Really add support for microblaze. A previous commit was lacking
the necessary line.
