Rustc expects to be provided both a search path `-L`, and a link arg `-l
kind=libname`, but we don't handle that correctly. Because we combine -L
and -l arguments from pkg-config the backend must rematerialize the -L
and -l split. We currently don't do this for static archives.

Rustc does not produce object files we can reuse to build both
libraries. Ideally this should be done with a single target that has
both `--crate-type` arguments instead of having 2 different build rules.
As temporary workaround, build twice and ensure they don't get conflicts
in intermediary files created by rustc by passing target's private
directory as --out-dir.
See https://github.com/rust-lang/rust/issues/111083.
While at it, make more methods private by storing the version found on
the instance. That avoids having to call check_pkgconfig() as static
method from unittests.
This also makes it more consistent with get_pkgconfig_variable() which
always return empty value instead of failing when the variable does not
exist. Linking that to self.required makes no sense and was never
documented any way.
The Metrowerks assembler does not support optimization flags.
However, it received the same opt args as the Metrowerks C and C++
compilers, because it inherits from the 'MetrowerksCompiler' mixin.
This broke builds with opt level higher than 0 that used the Metrowerks
Assembler, as the latter received unsupported args. This is now fixed.
According to the Meson documentation, optimization level 3 should
set the highest possible optimization for the compiler in use.
In Metrowerks, this is 'O4,p'. However, Meson's Metrowerks
implementation mapped opt level 3 to '-O3'. This has been fixed.
The args were in both buildtype and optimization. This broke buildtypes other
than plain or custom unless manually setting the optimization level to
0, because Metrowerks chokes on duplicate arguments.
The interpreter takes significant amount of time to initialize
everything in project() function. We only need to extract a string from
AST, just like we do in handle_meson_version_from_ast().
FIXME: another approach would be to consider cont_eol as comment (i.e.
add backslash and whitespaces to the comment regex). In both cases it
works until we want to parse comments separately.
TODO?: handle eol_cont inside a string (to split long string without
breaking lines). Probably a bad idea and better to simply join a
multiline string.
