arm: Avoid using solaris syntax for .section directive

Assembler from binutils 2.41 will rejects ([1], [2]) the following
syntax

.section "name", #alloc

for any other any target other than ELF SPARC. This means we can't use
it in the Arm code.

So switch to the GNU syntax

.section name [, "flags"[, @type]]
