Fix libc header dependencies Turns out we had a bunch of silly dependencies on libc headers that are not included with freestanding compilers. Fix all this and change the CFLAGS to exclude libc headers and only include the built-in compiler path. Add our own versions of assert.h, errno.h, limits.h, and move malloc.h and string.h together into a new path used as -isystem, so these headers can be included using #include <>. Remove a bunch of other dependencies in third-party code. Add a strnlen function. Disable building the libfdt overlay code for now, as it needs a strtoul implementation. We can throw that in if/when we decide to use overlays. Signed-off-by: Hector Martin <marcan@marcan.st> 2021-03-07 16:31:14 +00:00			`/* SPDX-License-Identifier: MIT */`
