d46753e421 [ELF] - Do --hash-style=both by default.
Its PR34712,

GNU linkers recently changed default values to "both" of "sysv".
Patch do the same for all targets except MIPS, where .gnu.hash
section is not yet supported.

Code suggested by Rui Ueyama.

e979fd1bf0 Don't put ro before rx when using linker scripts.
Since they end up going on the same PT_LOAD, there is no reason to
sort them. This matches bfd's behaviour and is user visible in the
placement of orphan sections.

b45fd70ef1 Disable --rosegment when we have linker scripts.
Linker scripts are responsible for aliging '.'. Since they are
designed for bfd which has no --rosegment, they don't align the RO to
RX transition.

aab6d5c52a Put SHF_ALLOC sections first, even with linker scripts.
This matches gold and bfd, and is pretty much required by some linker
scripts. They end with commands like

foo   0 : { *(bar) }

if we put any SHF_ALLOC sections after they can have an address that
is too low.

1d98d6292f Make sure we create all necessary PT_LOADs.
We were some times stopping early when using linker scripts.
