Subject: perf trace/scripting: Fix compile error when libperl not installed
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3a9a0beba2913edaae39ff8b4645fee10c3acf37;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

perf trace/scripting: Fix compile error when libperl not installed

When I added the xs callbacks into perf, I forgot to re-check
the no-libperl case. This patch fixes the undefined reference
error for that.
