could we just keep it simple for now?
When as root in bash session I do:
] gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/libexec/gcc/x86_64-redhat-linux/4.8.5/lto-wrapper
Target: x86_64-redhat-linux
...
But when crond does the same then COLLECT_LTO_WRAPPER is not 
there.
Is it possible to fix that first?
