Thanks for your feedback.

My understanding is that $PATH used to be set in ver_linux before. It
had been removed by the commit given below:

2008-07-31kbuild: scripts/ver_linux: don't set PATH
It would have saved both a bug submitter and me a few hours if
scripts/ver_linux had picked the same gcc as the build. Since I can't
see any reason why it fiddles with PATH at all this patch therefore
removes the PATH setting.

Perhaps a better approach would be for the user to set their $PATH
appropriately in their shell environment, rather than in ver_linux, as
suggested in the commentary found in ver_linux, instead of ver_linux
trying to guess where the binaries are. Which effectively makes my
other patch, path2bin_test.patch, redundant. Apologies for that.
