libsigsegv*: add an option to apply a patch
Close #28536; this code is a bit different in style for 2.5,
and avoids mass rebuild for the default version.

longDescription = ''
GNU libsigsegv is a library for handling page faults in user mode. A
page fault occurs when a program tries to access to a region of memory
that is currently not available. Catching and handling a page fault is
a useful technique for implementing pageable virtual memory,
memory-mapped access to persistent databases, generational garbage
collectors, stack overflow handlers, distributed shared memory, and
more.
