[BUG v2017.07.0] readlink -f command broken?

[Ian Abbott]

Hi folks,

I know there were changes to do with links to directories in v2017.07.0, 
but this looks like a bug in readlink with the -f option:

barebox at fred:/ ls -l /mnt/root
lrwxrwxrwx              7 bin -> usr/bin
drwxr-xr-x            304 boot
drwxr-xr-x            160 dev
drwxr-xr-x           1920 etc
drwxrwsr-x            160 home
lrwxrwxrwx              7 lib -> usr/lib
drwxr-xr-x            160 mnt
dr-xr-xr-x            160 proc
drwx------            160 root
drwxr-xr-x            160 run
lrwxrwxrwx              8 sbin -> usr/sbin
drwxr-xr-x            224 srv
drwxr-xr-x            160 sys
drwxrwxrwt            160 tmp
drwxr-xr-x            480 usr
drwxr-xr-x            544 var
barebox at fred:/ readlink -f /mnt/root/lib libdir
barebox at fred:/ echo $libdir
/usr

(I expected $libdir to contain "/mnt/root/usr/lib" here, as it did in 
barebox v2017.06.1.)

(Let's try it without the -f option....)

barebox at fred:/ readlink /mnt/root/lib libdir2
barebox at fred:/ echo $libdir2
usr/lib

(That is the same as barebox v2017.06.1.)
