qt5base-lts/tests/auto/qicon/tst_qicon.cpp
Rohan McGovern c07e1130d9 test: fixed failure of tst_qicon 
This test unconditionally assumed that SVG support was available.
This is an invalid circular dependency: the test is in qtbase and
depends on qtsvg, which depends on qtbase.

Change the test so that it uses SVG support only if available.
