Subject: [PATCH 2/2] perf tools: Fix fallback to cplus_demangle() when bfd_demangle() is not available

From: Conny Seidel <conny.seidel@....com>

make version 3.80 doesn't support "else ifdef" on the same line, also it
doesn't support unindented nested constructs.

Build fails with:
Makefile:608: Extraneous text after `else' directive
Makefile:611: *** only one `else' per conditional.  Stop.

This patch fixes the build for make 3.80.
