QEMU is now stricter with MMIO sizes and accesses. uintptr_t on RV64
is 8 bytes and generates an sd instruction that Store/AMO faults
because sifive_test MMIO expects 4 bytes accesses.
Add a feature to enforce an explicit target file for assembler sources.
Add a build start file node list and use it as a test program
dependency.
The fix for #3846 and #4080 needs to be combined, because the fix
for #3846 requires the removal of 'before=["cstlib"]'. This patch fixes
two issues:
1. The tracking of start file dependencies.
2. Reflect that executables depend on the start files.
We need a start.o file in the right path so that the linker can find is
as specified by the linker script, and not for example a start.S.17.o
file in some path. This part is addressed by the "explicit_asm_target"
feature.

Close#3846.
Close#4080.
In a multi-processor system we must broadcast the TLB maintenance operation to
the Inner Shareable domain to ensure that the other processors update their TLB
caches accordingly.
Close#4068.
Do the stack allocator initialization and sanity check only if a
user-provided stack allocator was configured. This avoids a dependency
of _Thread_Handler_initialization() on the stack allocator.
Update #3959.
Only provide the file descriptor array if
CONFIGURE_MAXIMUM_FILE_DESCRIPTORS > 0. If someone configured
CONFIGURE_MAXIMUM_FILE_DESCRIPTORS == 0 and the appplication uses
something which requires a file descriptor, then a linker error will
show up. An alternative would be to add a zero-length array
rtems_libio_iops[ 0 ] to librtemscpu.a which would be used in this
case.
Conditionally include some header files.
Remove the superfluous invalid name check since the object creation
directives ensure that objects with such a name cannot exist. Also
finding an object with such a name would be no catastrophy if it really
exists.
Simplify object name to identifier directives. Using
_RTEMS_Name_to_id() to implement the directives enables a tail call
optimization.
Change license to BSD-2-Clause according to file history.
Update #3053.
The argument to the ctype functions must be an int and the value of the
character must be representable as an unsigned char or equal to the
value of the macro EOF. If the argument has any other value, the
behavior is undefined.
