fe6b5c08dc configure: Use the environment variable CC when compiling tcc 
Using the environment CC is a common used feature to
select a compiler to build any software,
so it should be supported when building tcc.

The old way using the parameter --cc still works.

b3bebdb20a libtcc: Allow more values for the -std= option

who expect gcc or clang as compiler. (-std=gnu11 used in Makefiles)

As a further extension, it would be easy to disable gcc extensions

313855c232 Fix multi dimensional vla arrays on stack 
There is no code generation in post_type for vla arrays. This code
generation has to be delayed until gen_function.

- post_type save code in type info.
- gen_function use this code to generate vla code.
- enable testcode for vla arrays.

ec5d94291c tccgen: accept array-size expressions in function paramters 
Modify function parameter parser such that symbols are
put into token-table temporarily.  Benefits are:
- detects redefinitions, as with
    int foo(int a, int a);
- detects reserved symbols, as with
    int foo(int if);
- can parse expressions like
    int main(int argc, char *argv[argc + 1]);
- doesn't fix this one
    int main(int argc, char *argv[++argc]);

Also: fix unexpected "function might return no value"
with statement expression
    int f() { ({ return 0; }); }

ca11849ebb Permit '=' character in configure options 
By replacing the `-f 2` field selection with `-f 2-`, we select fields
2 and beyond, so that arguments containing the '=' character are not
truncated.

This option qualifier list format is POSIX standard and tested
to work with the `cut` program from:
* GNU coreutils
* macOS (FreeBSD)
* NetBSD
* toybox
* busybox
* uutils-coreutils

In my case, this is useful because I'm trying to use an installation
prefix which contains an equals sign.
