  [Multilib] Custom flags processing for library selection

Select library variants in the multilib system using the flags passed in
the '-fmultilib-flag=' format.

Multilib flags that were not passed in the command-line have their
default value  fed into the library selection mechanism.

A warning is shown if the flag's value is invalid. The closest valid
value is suggested (string edit distance).
