George Rimar 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.

George Rimar 8c658bf824 [ELF] - SEGMENT_START's default argument can be an expression
Our implementation supported integer value previously.
ld can use expression,
for example, it is OK to write
 . = SEGMENT_START("foobar", .);

Patch implements that.

Rafael Espindola 54c145ce0e Add support for SEGMENT_START.
This is a bit of an odd feature. It is normally used in

. = SEGMENT_START(seg, val);

In bfd it evaluates to val or to the value of the corresponding
-T<seg>-segment. Note that the -T<seg>-segment in bfd doesn't actually
change the segment address, just the value this evaluates too,
including in the default linker script.

In gold the -T<seg>-segment options do change the segment address and
seeing this expressions in linker scripts disables the options.

For new this just always evaluates the expression to val.
