bash: prevent aliasing of libc's 'getenv'

Browse Source 
By default, bash brings its own version of 'getenv', named exactly like
the libc function. This becomes a problem in fork/execve scenarios if
the dynamic linker resolves 'getenv' to the bash binary instead of the
libc.

This patch fixes the generate step of the genodians.org scenario.

Issue #3882
