While trying to raise an exception on failures, it instead raised an
exception for misusing the exception. CalledProcessError is only
supposed to be used when given a return code and a command, and it
prints:
Command '{cmd}' returned non-zero exit status {ret}
Passing an error message string instead, just errored out with:
TypeError: __init__() missing 1 required positional argument
Instead use the subprocess module's base error which does accept string
messages. Everything that used to error out, still errors out, but now
they do so with a slightly prettier console message.
libm is not guaranteed to exist. POSIX requires the math functions to
exist, but doesn't require to have it be a standalone library.
On platforms where libm exists as a standalone library, it will always
be found by meson -- it is shipped with libc.
If it is not found, then we can safely assume the linker will make the
math functions available by default.

Fixes building with bin_tests=true on Windows.
Regression from commit a5f2c45528. It is
not possible to unconditionally add the asm sources, since not all
compilers understand the .s file extension.
Specifically for meson, only compilers inheriting from the GNU mixin
will allow a .s file at configure time.
zstd doesn't support asm for MSVC for the same basic reason; if/when
Windows asm support is added, it would involve preprocessing with nasm,
most likely.
This matches the Makefile build. Due to one private xxhash symbol in use
by the program, it recompiles a private copy of xxhash.
Due to the test binaries making extensive (?) use of private symbols, it
doesn't even attempt to link to shared libzstd, and instead, all of the
original object files are added to libtestcommon itself for private
linkage. This, too, matches the Makefile build.
Ref. #2261
meson prefers that project-level options for Wall/Wextra/pedantic be
used, rather than hardcoding raw flags in add_project_arguments. If you
do the latter anyway, it raises a meson warning.
Set the default options for the project to use all this.
Also move the -Werror comment to the project default options with
appropriate format, but leave it commented out since it does not work.
