From: Ben Hutchings Date: Fri, 16 Aug 2024 15:58:04 +0200 Subject: perf tools: Pass EXTRA_CFLAGS through to libbpf build again When perf was statically linked to libbpf, any definition of EXTRA_CFLAGS passed to Makefile.perf propagated to the sub-make of libbpf. Since commit 9dabf4003423 ("perf python: Switch module to linking libraries from building source"), EXTRA_CFLAGS is overridden to "-fPIC" for the sub-make. Change to include any user-provided EXTRA_CFLAGS before the "-fPIC" option. Fixes: 9dabf4003423 ("perf python: Switch module to linking libraries ...")
