sys-libs/db: compile-fix by dropping mutex=ARM/gcc-assembly
This is a compile-fix so that old versions build on newer ARM hardware.
The ARM assembly code does not work on newer hardware
so you CANNOT use --with-mutex=ARM/gcc-assembly anymore.
Specifically, it uses the SWPB op, which was deprecated [1]
The SWPB op ALSO cannot be used in ARM-Thumb mode.
>=sys-libs/db-6.1 uses LDREX instead, but that fix CANNOT be backported
due differing licenses in the new versions (the new version is AGPL).
Trust the compiler instead for older sys-libs/db versions, and just drop
--with-mutex=ARM/gcc-assembly from the configure.
