not compatible with '_thread' module 
ulab not compatible with enabling '_thread' module from the make command :
- building ulab with thread enabled in MicroPython :
`$ make -j8 CFLAGS_EXTRA='-DMICROPY_PY_THREAD=1' BOARD=PYBV11 USER_C_MODULES=../../../ulab all`
yields a firmware with '_thread' module but without 'ulab' module, because 'CFLAGS_EXTRA' is used in the make command and in 'ulab/code/micropython.mk', so the value of the last is ignored;
- the solution is to use 'override' and '+=' in in last line of 'ulab/code/micropython.mk' :
`override CFLAGS_EXTRA += -DMODULE_ULAB_ENABLED=1`

d0b11a6081 polyfit: Argument handling improvements 
* In the 3-args case, the lengths of the arguments were not checked
 * in the 3-args case, the type of the 2nd argument was not checked
 * gcc falsely diagnosed a `maybe-uninitialized` variable because it
   did not see that the branches of the if() statement were mutually
   exclusive

It's this third issue that originally drew my attention to this code,

daf4b07ef7 Fix -Wunused-parameter diagnostics 
Here we actually get bugs fixed!  At many sites, mp_parse_arg_all's
first argument was the number of positional arguments required, rather
than the number actually supplied.

This fixes e.g., the bug where the linspace third positional argument
was not used as the "num" argmuent, and where too many positional args
were not treated as an error:

    >>> ulab.linspace(0, 1, 9)
    array([0.0, 0.125, 0.25, 0.375, 0.5, 0.625, 0.75, 0.875, 1.0], dtype=float)
    >>> ulab.linspace(0, 1, 1, 1)
    TypeError: extra positional arguments given

In the case of argmin/argmax of an iterable, it is now signaled to the user
that only the axis=None case is supported, instead of giving a wrong
result.

22605c6fe9 Fix -Wshadow diagnostics 
A declaration of a local variable can "shadow" a parameter or another
local variable declared in an outer scope.

Since this can create confusion about which variable is referred to, it
is better to fix these diagnostics.

A variety of changes were made:
 - Add curly braces to reduce the scope of a variable (ndarray_unary_op)
   so that its scope has ended before the next scope where it is used
 - be consistent about whether a variable is declared with for-loop scope
   or not (ndarray_print_row)
 - remove a declaration so that the outer variable is used, after verifying
   this will function properly (insert_slice_list)
 - rename a variable introduced by a macro (RUN_SUM, RUN_STD) so it does
   not shadow another variable

be1e2b28e0 Fix -Wmissing-prototypes diagnostics

11ed69dacf Fix -Wmissing-prototypes diagnostics 
This diagnostic flag, enabled by default in CircuitPython, requires that
nonstatic functions have a previous prototype.  Since placing prototypes
in header files is the only way that mismatched arguments between function
definition and use sites can be detected, this is a valuable warning.

In the case of ulab, the majority of the  changes required were to mark
functions as "static" that were used only in a single C source file.
