Compiler vendor not detected properly when using conda tools

[marcinz]

This is a repeat of #43 unfortunately. Conda has changed the version string on its compiler again:

$ $CC --version
x86_64-conda-linux-gnu-cc (conda-forge 11.2.0-15) 11.2.0
Copyright (C) 2021 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

This time, there is no GCC in the string, upper or lower case.

I am wondering if it would make sense to use ax_compiler_vendor?

Thanks for the suggestion @marcinz. I will make a simple patch for now (same comment applies as in #45), but I'll raise this suggestion in BLIS.

@marcinz please try 7d979b6.

We are going to change the version string to x86_64-conda-linux-gnu-cc (conda-forge gcc 11.2.0-15) 11.2.0. Sorry about the change.
