Bug#1017961: mozjs102: Fails to build on armel

[Jeremy Bicha <jeremy.bicha@canonical.com>]

Source: mozjs102
Version: 102.2.0-1
Severity: important
X-Debbugs-CC: debian-arm@lists.debian.org

mozjs102 fails to build on armel. This is a problem because it is
blocking us from being able to switch Debian's gjs to use mozjs102
instead of the obsolete mozjs91.

https://buildd.debian.org/status/logs.php?pkg=mozjs102&arch=armel

I did notice this repeatedly in the build log:

{standard input}: Assembler messages:
{standard input}: Error: selected processor does not support `dmb sy'
in ARM mode
{standard input}: Error: selected processor does not support `ldrexb
r0,[r1]' in ARM mode
{standard input}: Error: selected processor does not support `strexb
r3,r2,[r1]' in ARM mode

Thank you,
