That seems like it might work.
What is the effective default value of GCC_EXEC_PREFIX for the compiler
being tested if we don't set the variable?
Also, have you tested my suggested change to HOSTCC? If HOSTCC is
another GCC then any environment variables that affect the compiler
we're trying to test will also affect HOSTCC. It seems to me that the
best way to avoid that causing problems is to make sure that HOSTCC
sets/unsets the environment variables it needs.
