From: Wang Nan Date: Fri, 29 Jan 2016 05:57:30 +0000 (+0000) Subject: perf build: Remove all condition feature check {C,LD}FLAGS X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5a155bb77a673dda941121142d686c3f47b49981;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git perf build: Remove all condition feature check {C,LD}FLAGS 'make feature-dump' should give a stable result, so even 'NO_SOMETHING=1' is given (for babeltrace, if LIBBABELTRACE=1 is not given), we should try to detect those feature and {C,LD}FLAGS. Build or not should be controled independent.
