Many of the tests skipped platforms that build PIE binaries by
default, but (still) lack a central function to report which platforms
those are.
Some of the tests assumed (but did not check for) internal linking
support, or invoked `go tool link` directly without properly
configuring the external linker.
A few of the tests seem to be triggering latent bugs in the linker.

The minimum bootstrap version for Go ≥ 1.20 is Go 1.17. That version
supports the new style //go:build lines. Thus the old style //+build

Separate out the functions from cmd/internal/sys/support.go and
migrate them to a new package internal/platform, so that functions such as
"RaceDetectorSupported" can be called from tests in std as well as in
cmd. This isn't a complete move of everything in cmd/internal/sys;
there are still many functions left.
The original version of this CL (patch set 1) called the new package
"internal/sys", but for packages that needed both "internal/sys" and
"cmd/internal/sys" the import of the former had to be done with a
different name, which was confusing and also required a hack in
cmd/dist.
Updates #56006.

In CL 210180 we detect gaps between PT_LOAD segments and subtract
them from size calculation. The code there only works when
PT_LOAD segments are next to each other. But it is possible that
there are other segments in between (e.g. a GNU_RELRO segment).
Relax the gap detection to count gaps between PT_LOAD segments
regardless of whether they are next to each other.
