replace the "cd dir && ln" commands with a single ln command

[gerard@…]

Example:

cd $LFS/bin && ln -sf bash sh

Change to:

ln -s bash $LFS/bin/sh

Extend to other commands as well that 'cd' first before doing something.

Example: cd $LFS/usr/bin && mv bzcat bunzip2 bzip2 bzip2recover bzless bzmore $LFS/bin

Could become:

mv $LFS/bin/{bzcat,bunzip2,bzip2,bzip2recover,bzless,bzmore}

[gerard@…]

uhm make that:

mv $LFS/usr/bin/{bzcat,bunzip2,bzip2,bzip2recover,bzless,bzmore} $LFS/bin
