A regression was introduced on ARM bare-metal builds by selecting the XSLEEP_MS() implementation that calls nanosleep() whenever _POSIX_C_SOURCE >= 199309L is defined.
On the arm-none-eabi 13.2 toolchain, newlib predefines _POSIX_C_SOURCE=200809L, but does not provide nanosleep() so compilation fails with -Werror=implicit-function-declaration in wolftpm/tpm2_types.h. This surfaced while compiling wolfboot with latest wolfTPM.
