There is no secret, see
https://www.ibm.com/docs/en/ztpf/2022?topic=tasks-build-gnu-compiler-collection-ztpf-system,
third bullet point. Have your check book handy when you call.
My prior belief also didn't agree with those who are saying the rh move is
legal under the gpl. But, as I keep saying, I am NAL.

Your belief doesn't agree with the GPL version 3, which is the license for GCC.

5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to produce it
from the Program, in the form of source code under the terms of section 4,
provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified it, and
giving a relevant date.
b) The work must carry prominent notices stating that it is released under
this License and any conditions added under section 7. This requirement
modifies the requirement in section 4 to “keep intact all notices”.
c) You must license the entire work, as a whole, under this License to
anyone who comes into possession of a copy. This License will therefore apply,
along with any applicable section 7 additional terms, to the whole of the work,
and all its parts, regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not invalidate
such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive interfaces
that do not display Appropriate Legal Notices, your work need not make them do
so.

"Released under this License" includes providing source.
Providing source does not necessarily mean making it available to anyone.

6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms of sections 4
and 5, provided that you also convey the machine-readable Corresponding Source
under the terms of this License, in one of these ways:
a) Convey the object code in, or embodied in, a physical product (including
a physical distribution medium), accompanied by the Corresponding Source fixed
on a durable physical medium customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product (including
a physical distribution medium), accompanied by a written offer, valid for at
least three years and valid for as long as you offer spare parts or customer
support for that product model, to give anyone who possesses the object code
either (1) a copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical medium
customarily used for software interchange, for a price no more than your
reasonable cost of physically performing this conveying of source, or (2)
access to copy the Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the written
offer to provide the Corresponding Source. This alternative is allowed only
occasionally and noncommercially, and only if you received the object code with
such an offer, in accord with subsection 6b.
d) Convey the object code by offering access from a designated place
(gratis or for a charge), and offer equivalent access to the Corresponding
Source in the same way through the same place at no further charge. You need
not require recipients to copy the Corresponding Source along with the object
code. If the place to copy the object code is a network server, the
Corresponding Source may be on a different server (operated by you or a third
party) that supports equivalent copying facilities, provided you maintain clear
directions next to the object code saying where to find the Corresponding
Source. Regardless of what server hosts the Corresponding Source, you remain
obligated to ensure that it is available for as long as needed to satisfy these
requirements.
e) Convey the object code using peer-to-peer transmission, provided you
inform other peers where the object code and Corresponding Source of the work
are being offered to the general public at no charge under subsection 6d.
