Regenerating INSTALL

[ricaljasan <ricaljasan at pacific dot net>]

Getting to the final stages of preparing my patches, and I know INSTALL
needs to be regenerated and its patch included alongside install.texi,
but I am getting some unexpected diffs.  From
https://sourceware.org/glibc/wiki/Regeneration I see that `make INSTALL'
is supposed to take place.  However, I get a ton of hunks in the diff,
not just the few I expected.  An example of a relevant hunk is:

-'--disable-mathvec'
-     By default for x86_64, the GNU C Library is built with vector math
-     library.  Use this option to disable vector math library.

+`--disable-mathvec'
+     By default for x86_64, the GNU C Library is built with the vector
+     math library.  Use this option to disable the vector math library.

It appears that many of the hunks are related to the '-vs-` generation,
but there are many more, related to things such as an apparent
difference in line-width.  For example:

-setting up a chroot environment or preparing a binary distribution.  The
-directory should be specified with an absolute file name.  Installing
-with the 'prefix' and 'exec_prefix' GNU standard make variables set is
+setting up a chroot environment or preparing a binary distribution.
+The directory should be specified with an absolute file name. Installing
+with the `prefix' and `exec_prefix' GNU standard make variables set is
 not supported.

How should I deal with this?  Do I need to hand-pick the edits (`git add
-p'), or is it expected that I generate INSTALL before working on my
branch (maybe it is expected that I always `configure' first?) so I can
`make INSTALL' again afterwards to get only the relevant edits in the patch?

Thanks,
