Support AutoTools CC_FOR_BUILD variable

[klausholstjacobsen]

What is your suggestion?

Hello
Conan 2.0.16

I am cross building various packages.
I have both a build profile and host profile which both has tool_requires to their respective toolchain packages.
These toolchain packages define (among other things) tools.build:compiler_executables.
This works well in many cases.
But sometimes I come across packages that build with autotools and uses the CC_FOR_BUILD variable to find the compiler for the build host. These packages always find my system installed gcc. I do not want that.

I suggest that if I have a build profile that define tools.build:compiler_executables in the build context then AutoToolsToolchain should define the CC_FOR_BUILD variable to point to the compiler here.

Regards
Klaus
