GCC package: don't set CC etc. based on bin dir if it doesn't exist (#13000) 
7bcb306 updated setup_environment in the GCC package to examine the
bin/ directory to find alternatively-named instances of CC, but this
failed to account for when GCC was being installed and failed when
it attempted to list the not-yet-existing installation prefix. This
commit updates the logic to skip this search if the bin/ directory
doesn't exist.

# We specifically do not add 'all' variant here because:

# In that respect, the name 'all' is rather misleading.
# (ii) Languages other than c,c++,fortran are prone to configure bug in GCC
# For example, 'java' appears to ignore custom location of zlib
# (iii) meaning of 'all' changes with GCC version, i.e. 'java' is not part
# of gcc7. Correctly specifying conflicts() and depends_on() in such a
# case is a PITA.
