[PATCH 1/2] perf annotate: Remove s390 basr instruction from call table

[Thomas Richter]

Perf annotate displays function call assembler instructions
with a right arrow. Hitting enter on this line/instruction
causes the browser to disassemble this target function and
show it on the screen.

S390 assembler instruction 'basr %r1,%r2'
jumps to address stored in register 2. Since the
target address is unknown to perf it can not be handled.

Therefore remove the right arrow from such an instruction
as the target function can not be identified.
