Bug#873778: Fix for the mozjs52 build on armel

[Adrian Bunk]

Changes in this patch:

1. Remove --disable-methodjit, option is no longer available.

Sync compiler flags from firefox-esr:

2. Use -fno-schedule-insns also on armel.

3. Use "-fno-schedule-insns2 -fno-lifetime-dse -fno-delete-null-pointer-checks"
   on all architectures.

        of the darkness. There had been need of rain for many days.
       "Only a promise," Lao Er said.
