Re: [Tinycc-devel] test failure on Linux

After git pull on RPi I get:

$ make && make test
gcc -o libtcc.o -c libtcc.c -DTCC_TARGET_ARM -DWITHOUT_LIBTCC -DTCC_ARM_EABI

Actually maybe:
        echo "You don't have an usable compiler"

If we cannot compile that file then how could we compile TCC.

I'd suggest something "config-...", config-info/print/env or some such.
That it sorts near to configure in directory listing.

If #defined unconditionally overriding on the compiler command line doesn't
work any more.  Maybe you can use configure:print_var2().

CONFIG_LDDIR is now undefined in tcc.  Leaving "lib" as default cannot hurt
IMO (even if it's just to keep the section readable).

The eval messes up with ./configure --extra-cflags="-Os -Wall"

ldd doesn't work on my MSYS. I cannot complain because I just have the
downstripped version for git, but maybe you can use
        gcc -print-file-name=crt1.o
or such.
