202406022310Z/images/NetBSD-10.99.10-mac68k.iso is 667,525,120 bytes
so it still fits to 700MB, but macppc one doesn't and even for mac68k
with '-m debug.tgz -m xdebug.tgz' generates 339,959,808 byte iso.

I'll commit the change soon:

Several ports that have bootable installcd call ${TOOL_INSTALLBOOT}
against generated iso images (by makefs(8)):

 https://github.com/NetBSD/src/blob/791da06d/distrib/alpha/cdroms/installcd/Makefile#L8-L10
---
#make the CD bootable
image_md_post:
	${TOOL_INSTALLBOOT} -m${MACHINE} ${CDIMAGE} bootxx.${MACHINE}
---

This ${CDIMAGE} target is created in ${.OBJDIR} and it's copied
into ${CDROMS_RELEASEDIR} later in MI "iso_image" target in
src/distrib/common/Makefile.bootcd:

  https://github.com/NetBSD/src/blob/791da06d/distrib/common/Makefile.bootcd#L347-L349
---
iso_image: prepare .WAIT prepare_md_post .WAIT copy-releasedir .WAIT image_md_pre .WAIT image .WAIT image_md_post
	${MKDIR} ${MKDIRPERM} ${RELEASEDIR}/${CDROMS_RELEASEDIR}
	${RELEASE_INSTALL} ${CDIMAGE} ${RELEASEDIR}/${CDROMS_RELEASEDIR}
---

In the perfect world[TM], we should merge mkisofs/mkhybrid iso targets
in etc/Makefile to src/distrib/common/Makefile.bootcd :-)
