Currently, on Mach-O, the Go linker doesn't generate LC_UUID in
internal linking mode. This causes some macOS system tools unable
to track the binary, as well as in some cases the binary unable
to access local network on macOS 15.
This CL makes the linker start generate LC_UUID. Currently, the
UUID is generated if the -B flag is specified. And we'll make it
generate UUID by default in a later CL. The -B flag is currently
for generating GNU build ID on ELF, which is a similar concept to
Mach-O's UUID. Instead of introducing another flag, we just use
the same flag and the same setting. Specifically, "-B gobuildid"
will generate a UUID based on the Go build ID.
Updates #68678.
Fixes #69992.

The test directory contains tests of the Go tool chain and runtime. It includes black box tests, regression tests, and error output tests. They are run as part of all.bash.
To run just these tests, execute:
../bin/go test cmd/internal/testdir
To run just tests from specified files in this directory, execute:
../bin/go test cmd/internal/testdir -run='Test/(file1.go|file2.go|...)'
Standard library tests should be written as regular Go tests in the appropriate package.
The tool chain and runtime also have regular Go tests in their packages. The main reasons to add a new test to this directory are:
- it is most naturally expressed using the test runner; or
- it is also applicable to
gccgoand other Go tool chains.
