Browse Source 
Do not inherit autotools bbclass, the configure script is hand-written
and not a autoconf generated one.

Subject: [PATCH] build: Fix a build error on i386
It happened to have common.S as well as common.c, so it picked the .S
before .c for the uftrace-arch.a. And it caused undefined symbols.
/usr/bin/ld: libmcount/symbol.op: in function `load_dynsymtab':
utils/symbol.c:722:(.text+0x2b19): undefined reference to `uftrace_arch_ops'
libmcount/symbol.op: in function `load_elf_dynsymtab':
utils/symbol.c:586:(.text+0x184a): undefined reference to `uftrace_arch_ops'
Fixed: #2010
Upstream-Status: Backport [https://github.com/namhyung/uftrace/commit/ea53a7f42c1c5da688ef79e53731dcc3810a1256]
