Bug#1108621: skycat: Prospective upgrade of blt to 3.0 affects skycat

[Ole Streicher]

Hi Sergei,

my understanding of your patch is that it is not backward-compatible, 
right, because the library name changed in BLT_LIBFLAG? i.e. I can only 
apply it once you made the upload of blt-3.0, right?

Best

Ole
