Hi folks,

I encountered a build error when using ptxdist-2017.07.0 with 
OSELAS.Toolchain-2014.12.2 (specifically, the 
"oselas.toolchain-2014.12.2-arm-v7a-linux-gnueabihf-gcc-4.9.2-glibc-2.20-binutils-2.24-kernel-3.16-sanitized" 
Debian package) to build barebox_mlo for an Altera SoCFPGA target.


Here are the last few lines of the build output:

   LDS     images/pbl.lds
   LZO     images/barebox.z

The "invalid magic" message comes from the "fix_size" program executed 
by "images/Makefile".  It seems to be caused by the presence of a 
".note.gnu-build-id" section before the the ".text" section in the 
"start_socfpga_socrates_xload.pbl" file, as shown by 
"arm-v7a-linux-gnueabihf-objdump -h start_socfpga_socrates_xload.pbl":

start_socfpga_socrates_xload.pbl:     file format elf32-littlearm

(In a working build, the ".text" section starts at offset 00008000 and 
there is no ".note.gnu.build-id" section.)


The problem does not occur with ptxdist-2017.06.0.  I upgraded to 
2017.07.0 because I was getting Perl errors with automake-1.15 after 
upgrading my Debian "testing" (buster/sid) system.

Also, the problem does not occur with OSELAS.Toolchain-2016.06.1 (Debian 
package 
"oselas.toolchain-2016.06.1-arm-v7a-linux-gnueabihf-gcc-5.4.0-glibc-2.23-binutils-2.26-kernel-4.6-sanitized"). 
  I use the older toolchain because it produces smaller binaries and I'm 
a bit short on space in flash memory.

I've attached a pretty minimal set of project files in case anyone feels 
like trying to reproduce it.  The files are:

configs/ptxconfig
configs/ebv-socrates/barebox_mlo-config
configs/ebv-socrates/platformconfig


I'll continue my investigation tomorrow to find out what is causing the 
".note.gnu.build-id" header to appear in the .pbl file.

Thankyou for your time, and for PTXdist!
