On x32 builds, sysd-syscalls appears malformed since the make-target-directory
appears on the wrong line. This causes races during the build process where you can
see failures like:
Assembler messages:
Fatal error: can't create [...]glibc/2.21-r0/build-x86_64-poky-linux-gnux32/time/gettimeofday.os: No such file or directory
Assembler messages:
Fatal error: can't create [...]glibc/2.21-r0/build-x86_64-poky-linux-gnux32/time/time.os: No such file or directory
The isue is that the carridge return is being escaped when it should
not be. The change to sysd-syscalls with this change:
before:
"""
$(foreach p,$(sysd-rules-targets),$(objpfx)$(patsubst %,$p,time).os): \
$(..)sysdeps/unix/make-syscalls.sh $(make-target-directory)
(echo '#include <dl-vdso.h>';
"""
after:
"""
$(foreach p,$(sysd-rules-targets),$(objpfx)$(patsubst %,$p,time).os): \
$(..)sysdeps/unix/make-syscalls.sh
$(make-target-directory)
(echo '#include <dl-vdso.h>';
"""
which ensures the target directory is correctly created. Only x32 uses the vdso
code which contains the bug which is why the error only really appears on x32.
