  On FreeBSD, make defconfig generates the config as "defconfig_x86_64-bsdapp-",
which does not resolve to any known config file.

This fix starts by introducing a 'compiler' variable which is set by executing
"${CC} --version" and pulling out the name of the compiler.

On FreeBDS, we get amd64 out of "uname -m", which was not handled by the list
of checks, but which now resolves to x86_64-native

The remaining code in the patch then takes ${compiler}, the "uname -m"
output and assembles them all together into a valid freebsd config name,
i.e. "defconfig_x86_64-native-bsdapp-clang"

Fixes: bce6c42c4ad5 ("mk: add sensible default target with defconfig")

You should not invoke a shell command outside of a rule.
Please try to move it inside the defconfig context.

Reason for this query?
1/ avoid polluting the rest of the makefile
2/ it breaks doc compilation

Why it breaks doc?
Because it breaks "make -R showversion" which is called in doc/guides/conf.py.
Tip: CC is not always defined :)
