Re: [patch] test-in-container: fix Arch Linux build-programs bug?

Hi,

From commit 561b0bec444 onward, my cross-build for ARM target from X64
host started failing with the following error:

/home/3adev/src/siemens/y2038/glibc/build/support/links-dso-program.o:
file not recognized: Format de fichier non reconnu

(build is French; this means unrecognized file format)

Doing a

	$ file support/*.o

Results in:

support/echo-container.o:    ELF 32-bit LSB relocatable, ARM, EABI5
version 1 (SYSV), with debug_info, not stripped
support/links-dso-program.o: ELF 64-bit LSB relocatable, x86-64,
version 1 (SYSV), with debug_info, not stripped
support/shell-container.o:   ELF 32-bit LSB relocatable, ARM, EABI5
version 1 (SYSV), with debug_info, not stripped
support/stamp.o:             empty
support/test-container.o:    ELF 32-bit LSB relocatable, ARM, EABI5
version 1 (SYSV), with debug_info, not stripped
support/true-container.o:    ELF 32-bit LSB relocatable, ARM, EABI5
version 1 (SYSV), with debug_info, not stripped

Apparently, links-dso-program.o is built native for x86-64 then linked
for ARM.

Did the way to cross-build change with the advent of test-in-container?
