RTEMS Tools Build with Recent Newlib

[Joel Sherrill <joel@rtems.org>]

Hi

I bumped the newlib hash to the following in the RTEMS tools recipes:

commit 502cf4b7b5b79b83e8f41b4074212f9e27753f0b (HEAD -> master,
origin/master, origin/HEAD)

    libgloss: fix more missing dir with parallel install

    Depending on the processing order of rules when installing in parallel,
    these install rules might be processed before some other rule happens
    to create the respective dirs.  Make sure each one creates the needed
    dirs before installing into them.

And tried to build the following architectures:

aarch64 arm bfin i386 lm32 m68k microblaze mips moxie nios2 or1k
powerpc riscv sh sparc64 sparc v850 x86_64

arm, i386, and riscv did not complete the tool chain build.

All three architectures failed with multiple files having errors like these:

In file included from
../../../../../../gnu-mirror-gcc-40ccb47/newlib/libm/machine/arm/s_floor.c:39:
../../../../../../gnu-mirror-gcc-40ccb47/newlib/libm/machine/arm/../../math/s_floor.c:65:10:
fatal error: fdlibm.h: No such file or directory
   65 | #include "fdlibm.h"
      |          ^~~~~~~~~~
compilation terminated.
make[5]: *** [lib_a-s_floor.o] Error 1

fatal error: math_config.h: No such file or directory
   37 | #include "math_config.h"
      |          ^~~~~~~~~~~~~~~

I didn't proceed with building RTEMS or our tests but will once all
tool chains are building.
