Builds for 32-bit perf binaries on a 64-bit host currently fail with this error: [...] bench/../../../arch/x86/lib/memcpy_64.S: Assembler messages: bench/../../../arch/x86/lib/memcpy_64.S:29: Error: bad register name `%rdi' bench/../../../arch/x86/lib/memcpy_64.S:34: Error: invalid instruction suffix for `movs' bench/../../../arch/x86/lib/memcpy_64.S:50: Error: bad register name `%rdi' bench/../../../arch/x86/lib/memcpy_64.S:61: Error: bad register name `%rdi' ... The problem is the detection of the host arch without considering passed in flags. This change fixes 32-bit builds via: make EXTRA_CFLAGS=-m32 and 64-bit builds still reference the memcpy_64.S.
