Tiago Medicci Serrano	58e97e521c	libc/string: prevent libc in the kernel/userspace optionally ... Add the `LIBC_PREVENT_STRING_KERNEL` and `LIBC_PREVENT_STRING_USER` that are meant to be selected by the chip if no libc implementation is going to be built. If selected, neither NuttX's software version of the libc nor any architecture-specific implementation will be built in the kernel or in the userspace, respectively. In this case, the linker may provide a ROM-defined version of the libc functions instead.	2023-05-17 13:58:48 +08:00
