[build] Allow assembler section type character to vary by architecture
On some architectures (such as ARM) the "@" character is used as a
comment delimiter. A section type argument such as "@progbits"
therefore becomes "%progbits".
This is further complicated by the fact that the "%" character has
special meaning for inline assembly when input or output operands are
used, in which cases "@progbits" becomes "%%progbits".
Allow the section type character(s) to be defined via Makefile
variables.
