Good morning  Sibu,
It seems that you are building a LFS (linux from scratch), as a quick try to fix it; maybe some of the libs of qt* are not available on the other builds; I will suggest you to get the integrated mxe-octave , configure it ( --enable-octave=stable ,alpha or default) and like this you can run #make qt and looking into the logs you could see the flags/arguments used on the build process. When its done you could link to the */lib/ generated and if your lfs has no problems that should work.
Hope that helps.

Yours sincerely,  Chechu
