Slackware :: SlackBuild Rebuilds Everything Including The Actual Boot Loader With 'make -j4'?

I want to update syslinux to version 4.03 on my system, so I took a look at the SlackBuild.

I noticed that the SlackBuild rebuilds everything including the actual boot loader with 'make -j4', but there's a note in the docs directory (distrib.txt) that asks not to do that:

For creators of Linux distributions:

Syslinux is a notoriously hard program to debug, since it runs outside of any operating system, and has a tendency to expose BIOS and hardware bugs on various systems. Therefore, I would appreciate if you would resist the temptation of recompiling the Syslinux bootloader itself (ldlinux.asm) if at all possible. If you do that, I will have to refer any bug reports I receive back to the respective distributor.

However, I have no such concerns about recompiling the installer programs, and in fact, with both libc 5 and libc 6 in common use in the Linux world today I understand if you wish to relink the Linux-based installer against your system version of libc. Therefore a special makefile targets "make installer" has been included with the Syslinux distribution, starting with version 1.42.

To rebuild the installer programs *only*, starting from a freshly untarred distribution copy of Syslinux, do:

make clean
make installer

If you want to remove all intermediate files, including the ones obtained from assembling ldlinux.asm and which are included in the distribution, do "make spotless".

I thought I'd report this in case it was unnoticed by Pat and the team. If not I apologize for wasting your time
