CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT=y : NuttX EABI buildroot toolchain
CONFIG_CXX_NEWLONG=y : size_t is long (maybe?)
This is easily changed by modifying the configuration.
NOTE: When I used a recent CodeSourcery toolchain, then toolchain
generated an illegal blx to an even address when calling into one
of the EABI math libraries. I don't know why this happened or if
the probably is repeatable with other CodeSourcery versions. You
can try for yourself setting:
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery under Windows
CONFIG_CXX_NEWLONG=n : size_t is unsigned int (maybe?)
3. In addition to the the kernel mode build, this NxWM configuration
