Subject: build: Remove redundant AC_CONFIG_AUX_DIRS

There's an invocation of AC_CONFIG_AUX_DIR(build-scripts) at the top of
the file, which is sufficient. AC_CONFIG_AUX_DIRS is an undocumented,
internal version of AC_CONFIG_AUX_DIR that takes a whitespace-separated
list, instead of a single path to add to the list.

Newer versions of autoconf treat the argument to AC_CONFIG_AUX_DIRS
as being literal (they do not expand the shell variable), causing
autoreconf to fail. The argument to AC_CONFIG_AUX_DIR is documented
to be relative to $srcdir anyway, so there is no need to specify $srcdir
a second time.

Part of commit 614326ff "autotools build system updates" upstream.
