ARC: Make sure .ivt section is not purged by garbage collector
Fixes commit fac4790491f6 ("arc: Eliminate unused code and data with GCC's garbage collector"),
see [1].
Since in case of ARCv2 .ivt only contains addrresses of
interrupt/exception handlers linker doesn't understand that this section
actually make a lot of sense and decides to get rid of it if we use
"--gc-sections".
And KEEP does exactly this, see [2].
