cmd/6l: No .debug_gdb_script section in ELF

[gopherbot]

by erik.westrup:

The resulting ELF produced does not contain a ".debug_gdb_script" section.
Thus no Go runtime support for Go is loaded when running the ELF in GDB.


> What does 'go version' print?

go version devel +e3ff5d42017d Mon Mar 10 07:57:58 2014 +0100 linux/amd64

> What steps reproduce the problem?
1. $ hg clone -u release https://code.google.com/p/go
   $ cd go
   $ hg update default
   $ src/all.bash
2. $ go build hello.go
3. $ readelf -S hello | grep -c debug_gdb_script
   0

> What happened?
No debug gdb script path included.

> What should have happened instead?
$ readelf -S hello | grep -c debug_gdb_script
1
which happens on the release-branch.go1.2 branch.


> Please provide any additional information below.
Has the way of loading the debug_gdb_script changed intentionally?

Comment 3:

I think this can be closed as a duplicate of #6963, as the debug_gdb_script section is
only used for runtime-gdb.py.
