Subject: package/perf: use correct definition of ARCH on x86_64
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1b787822fbf3cda83eb7ef28c1187af6f6247781;p=buildroot.git

package/perf: use correct definition of ARCH on x86_64

LINUX_MAKE_FLAGS defines ARCH=$(KERNEL_ARCH), and KERNEL_ARCH is x86_64 on
a 64-bit x86 kernel build. The perf Makefiles expect that the ARCH will be
"x86" on both 32-bit x86 and 64-bit x86.

I didn't experience issues with the Linux 3.14.x version of perf, but this
issue cropped up once I started building 3.19.x.
