a3da3c32c1 Makefile.am: don't confuse CFLAGS and CFLAGS_FOR_BUILD
Commit dc427d50d9 enabled a number of extra
warning flags through configure.ac.  The configure script will determine
dynamically if CC supports these flags before adding them to WARN_CFLAGS.

ioctlsort is compiled with CC_FOR_BUILD, rather than CC.  Nevertheless,
the flags passed to this compilation also include WARN_CFLAGS (through
AM_CFLAGS).  This is incorrect: in a cross-compilation use case, CC
and CC_FOR_BUILD are not the same.  The former is the cross-compiler,
the latter is the host compiler.  Both may be of different versions
and support different warning flags.

In particular, this posed a problem when cross-compiling with a host
compiler gcc 4.1, which does not support all the new flags:

    /usr/bin/gcc -DHAVE_CONFIG_H   -I./linux/arm -I./linux/arm -I./linux
    -I./linux -I. -I. -I/host-sysroot/usr/include -Wall -Wempty-body
    -Wformat-security -Wignored-qualifiers -Winit-self -Wlogical-op
    -Wmissing-parameter-type -Wnested-externs -Wold-style-declaration
    -Wold-style-definition -Wsign-compare -Wtype-limits -Wwrite-strings -O2

cdeb5dda0a AX_PROG_CC_FOR_BUILD: redirect more variables related to C compiler
Some of these variables cannot be redirected using traditional

51694267bd tests: fix expected output in strace-ttt.test
If strace -ttt is running too long, it might happen that time stamps
before and after its invocation differ for more than a second.
Adjust expected output to handle this rare but possible case.

* tests/strace-ttt.test: Allow any time stamp between start and finish
of strace invocation.
