I did a test:
$ ln -s /usr/bin/ccache /folk/lyang1/bin/gcc
I got errors with/without the code:
$ bitbake -p
bb.BBHandledException
ERROR: Error running gcc --version:
I've sent a patch to fix/explain this problem:
[OE-core] [PATCH 0/1] lib/oe/utils: Set stderr for host_gcc_version()

$ ls -l tmp/hosttools/gcc
tmp/hosttools/gcc -> /folk/lyang1/bin/gcc
$ ls -l /folk/lyang1/bin/gcc
/folk/lyang1/bin/gcc -> /usr/bin/ccache
It worked well if I run gcc --version manually:
$ gcc --version
gcc (Ubuntu 5.4.0-6ubuntu1~16.04.10) 5.4.0 20160609

$ echo $?
0
There must be something wrong in such a case. I will fix this later.
Let's get back to he code:
srctool = bb.utils.which(path, tool, executable=True)
if "ccache" in srctool:
srctool = bb.utils.which(path, tool, executable=True,
direction=1)
if srctool:
os.symlink(srctool, desttool)
* If tool == "gcc", then srctool would be gcc, too.
* If tool == "ccache", then srctool would be ccache, too.
So I think that the code doesn't help when gcc links to ccache ?
