As Mike Frysinger notes, this code is still needed. I
misread this code and removed it, sorry.
I printed the values of _dl_brkp and _dl_envp in ldso and
got this when executing:
ls:
__curbrk: 0x300c16e0
__environ: 0x1008372c
ldd:
__curbrk: 0x300776e0
__environ: 0x3007759c
why is__environ in the app when executing ls but not ldd?
