Javier Viguera 0dccde0190 functions: avoid CR when progress bar is not enabled
Using CT-NG with progress bar disabled, still prints CR ('\r') characters
on the output. When you capture the output to a file as part of an
automated build, it shows extra empty lines.

For example:

------------------------------------------------------------
[INFO ]  Performing some trivial sanity checks

[INFO ]  Build started 20110404.113619

[INFO ]  Building environment variables

[EXTRA]  Preparing working directories

[EXTRA]  Installing user-supplied crosstool-NG configuration
