Patch to make sysconf always return ARG_MAX
When uClibc's getconf utility is installed, and uClibc is not built for
threads, GNU autoconf scripts will malfunction when determining the maximum
length of command-line arguments.
This is because uClibc's sysconf() returns -1, causing getconf to print
"undefined". The autoconf scripts cannot tolerate a non-numeric response
there.
Attached is a patch that forces sysconf to return legacy_ARG_MAX as a last
resort, rather than -1.
