[Patch] test_summary: handle single quotes

[Christophe Lyon]

Hi,

We happen to build GCC with '~' in the src and build dirs, leading to
single quotes around the configure path in config.status. For example:
[...]
S["TOPLEVEL_CONFIGURE_ARGUMENTS"]="'/home/christophe.lyon/src/Linaro/abe/abe-contrib-summary/mybuild/snapshots/gcc.git~linaro~gcc-7-branch/configure'
SHELL=/bin/bash --with-mpc=/home/"\
[...]

This confuses contrib/test_summary which matches "/configure .* in its
awk script, which fails to match when we have "/configure' XXX"
instead.

This patch fixes that by adding matches for the optional single
quotes. I use \047 to match the ascii "'", because I couldn't find how
to quote this properly in the awk script.

OK for trunk?

Thanks,

Christophe
