[ELDK] [PATCH] eldk-switch.sh: Handle empty lines in environment script

[Thomas Lange]

ELDK v5.8 includes an empty line in environment-setup-*
which caused this:

  k33:~$ eval `eldk-switch.sh -r 5.8 armv7a-hf`
  Setup for armv7a-hf (using ELDK 5.8)
  bash: syntax error near unexpected token `;'

So remove all empty lines before substituting <newline> with ;
