[Buildroot] [Bug 3703] Consider using /usr/bin/env bash in scripts

[bugzilla at busybox.net]

https://bugs.busybox.net/show_bug.cgi?id=3703

--- Comment #2 from holger+br at freyther.de  ---
I am hacking my way... so here is my incomplete list
I do have symlinks to help me.. with GNU coreutils
  mktemp -> gmktemp
  sed -> gsed
  install -> ginstall

uclibc fails to build a host utility... but on the second gmake just
continues...
  HOSTCC utils/ldconfig.host
In file included from ../utils/ldconfig.c:170:
../utils/readsoname2.c: In function 'readsoname32':
../utils/readsoname2.c:3: warning: implicit declaration of function 'ElfW'
(and more pointers to Elf names)


busybox fails with a include of shadow.h (not present on FreeBSD)

so I do have a basic gcc/uclibc toolchain for mips right now with the below
hacky changes
