[ptxdist] ld-wrapper mislinks at91bootstrap

[Ladislav Michl]

Hi there,

I just added new platform (at91) to my BSP and configured at91bootstrap
v3.8.9.

Problem is that PTXDist-2017.10 produces way too large binary:
2099622 at91sam9260ek-dataflashboot-barebox-3.8.9.bin
while correct size is:
   2470 at91sam9260ek-dataflashboot-barebox-3.8.9.bin

Problem turned out to be ld-wrapper script or something it calls.
Just replacing ld-wrapper in ptxdist-2017.10.0/scripts/wrapper to point
directly to arm-v5te-linux-gnueabi-ld is enough to solve problem.
Does anyone clue where to look? Call path is:
sysroot-host/lib/wrapper in $PATH where
arm-v5te-linux-gnueabi-ld -> ptxdist-2017.10.0/scripts/wrapper/ld-wrapper

Thank you,
ladis

[ptxdist] [PATCH 0/2] ptxdist: pkg-config changes

[Clemens Gruber]

Hi,

this is a first attempt at fixing the problems with the hardcoded
libraries, occuring on ArchLinux (before ncurses 6.0+20170902-3).

As a solution, now we detect ncurses and its sublibraries panel and menu
through pkg-config. The --with-ncurses argument can still be used to
prepend the include search path. (If that is no longer necessary / not
used in practice, I can drop it in v2)

I also added some additional checks, recommended by autoscan 2.69, in
the 2nd commit.

Cheers,
Clemens

Clemens Gruber (2):
  ptxdist: Use pkg-config for ncurses detection
  ptxdist: Add more checks, recommended by autoscan

So, ld-wrapper is adding:

Modifying at91bootstrap's Makefile to do --remove-section=.note.gnu.build-id
fixes it.

Are there other options to fix this?

Well, I'll fix upstream the same way kernel handles this.
Kernel is always right: https://lkml.org/lkml/2011/12/15/162
Another option is to use u-boot way, ie. nicely align a embed
this section into binary, but as every byte matters here, lets
not do this.
