[PATCH v2] arm32: Avoid using solaris syntax for .section directive

[Khem Raj <raj.khem@xxxxxxxxx>]

Assembler from binutils 2.41 rejects [1] this syntax

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

where flags could be #alloc, #write, #execinstr, #exclude, and #tls [2]

It is almost like a regression compared to 2.40 or older release,
It likely went unnoticed so far because Linux kernel changed
to GNU syntax already in 5.5, to allow building with Clang's
integrated assembler.

Switch to using GNU syntax

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