[OE-core] [PATCH 2/3] socat: fix supporting cross compiling

[Hongxu Jia]

The do_configure failed:
...
|checking for equivalent simple type of size_t... configure:
error: in `tmp/work/core2-64-poky-linux/socat/1.7.2.4-r0/build':
|configure: error: cannot run test program while cross compiling
...

For 1.7.2.4, the linux GCC check in configure.in didn't support
cross compiling, but the old version 1.7.2.3 supported, so we
reference 1.7.2.3 to fix this issue.
