only #include <xlocale.h> when it is actually needed
Backport of 68f1b6d700b9662cfdec43ceddbd086d4b59c87e
This header was originally only needed for builds on darwin and
FreeBSD, but was being included whenever it was detected.
This has caused problems when what was an internal header was
removed (from glibc) and in general wasn't needed anyway.
On FreeBSD only localeconv_l() requires xlocale.h, so we test
specifically for that.

prevent undefined behaviour at a language level while probing getenv
Backport of a5823872283be23731f1bcde7e19a926c44b31a4
This test in Configure tries to probe for undefined behaviour in
getenv (), but provokes undefined behaviour in C/C++ by falling off
the end of a function with a non-void return type.
Without optimization clang++ generated a ud2 instruction here on
amd64 producing an illegal instruction exception. With optimization
the test case fell off the end and started re-executing main (),
eventually producing a SIGBUS.
Simply dropping the value of getenv () here and returning NULL wasn't
useful, under -O2 the compiler optimized away the getenv () call,
voiding the whole point of the test.

good behavior. This adds a simple probe to test the current system.

Trap SIGBUS when Configure checks for va_copy (#18148)
On several systems the attempt to determine if we "need va_copy() or
similar" results in a SIGBUS instead of a SIGSEGV because the fault
happens pointing at an io device address.
While reviewing accounting logs during the OpenBSD system build, bluhm@
noticed a core dump and deraadt@ tracked it down.
While researching it was discovered that this is a fairly common case in
other systems as well.

Change Gconvert checkit() prototype for [perl #134371].
In the checkit() routine inside Configure, clang++ was taking the

the checkit() function never returned a value, so relabel it as void.

- because value is reused from previous configure run
And when the prefix is different from the previous configure run(*) then
keep the value of "none". predefined/cached value does not contain the
old prefix so there is no harm in keeping it.

old prefix so there is no harm in keeping it.
(*): due to another bug this also happens when prefix ends with a
trailing slash

Remove trailing '/' from prefix
Change how/when the trailing '/' from a prefix is removed.
The original code had two problems:
1) it only stripped the trailing slash when value was predefined
(either from -Dprefix=/foo/bar/ or from a previous configure run)
2) when it did strip the value then it also caused 'oldprefix' to
be set. This in turns causes other predefined (/cached) paths to
be ignored.

Backport improvements to setlocale() probe
This is from Perl 5 commit 2e3ef32f4acc106de6ae8170099f09a36d4ef490, but
with a couple of changes to appease the metaconfig linter by avoiding
strings of the form /\w+=\S+/ (which it interprets as attempts to set shell
variables).
