perf tools, x86: Fix 32-bit compile on 64-bit system
commit 08a4a43fc407d780bdde36d98f89c0dbb2a6be6b upstream.
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.
