gawk: ensure cross compiling doesn't try to remove host files

Fixes [YOCTO #6440]

When cross compiling gawk, it is possible to see this fail:

make[4]: Entering directory '/mnt/home/paul/poky/build/tmp/work/corei7-64-poky-
linux/gawk/4.1.1-r0/build/extension'

Makefile:1235: recipe for target 'install-data-hook' failed

The problem only manifests itself on hosts where the above files
are already present; for if they are absent then the rm -f does
not fail with -EPERM.

Before looking in mainline gawk for a fix, I fixed it myself.
Then in comparing with mainline gawk, I found their fix was
not 100% complete.  So here we get a backport of the mainline
gawk commit, plus the delta as a commit that I've sent to the
gawk mailing list.

+Subject: [PATCH] extension: Add $(DESTDIR) prefix to remaining pkgextensiondir
+ instances
+
+Commit 976f73ab03569bb836aa5c949be1c1cc973b2d2e ["Use $(DESTDIR) in
+extension/Makefile.am when removing .la files."] fixed an issue
+that manifested itself as follows when cross compiling:
+
+make[4]: Entering directory 'gawk/4.1.1-r0/build/extension'
+for i in filefuncs.la fnmatch.la fork.la inplace.la ordchr.la readdir.la readfi
+le.la revoutput.la revtwoway.la rwarray.la testext.la time.la ; do \
+        rm -f /usr/lib/gawk/$i ; \
+done

+rm: cannot remove '/usr/lib/gawk/time.la': Permission denied
+Makefile:1235: recipe for target 'install-data-hook' failed
+
+The problem only manifests itself on hosts where the above files
+are already present; for if they are absent then the rm -f does
+not fail with -EPERM.  The fix in 976f73ab0356 ensured that DESTDIR
+was used for the prefix so that it didn't try to delete host files.
+
+However there still remains less used instances of where it is used
+w/o $(DESTDIR) that may still cause similar breakage in the future.
+Here we apply the same change to them.
