Description

grub and loader builds both invoke the GNU linker (gld) during their build but assume that the linker's default output mode is 32-bit.

As distributions move towards 64-bit-by-default tooling, the required output format must be specified.

For example, on the latest OmniOS bloody, errors such as the following occur during the build:

/usr/bin/gld -g  -nostdlib -N -Ttext 7C00 -o stage1.exec stage1.o
/usr/bin/gld: i386 architecture of input file `stage1.o' is incompatible with i386:x86-64 output

i have proposed it a long time ago, but had no feedbacks:

I did it slightly differently, but the same idea:

Testing notes.

With this patch applied, I built illumos-gate on OpenIndiana, OmniOS r151032 and OmniOS bloody.

The GNU ld (gld) binary on each of these uses the following default output format:

OpenIndiana$ gld --print-output-format
elf32-i386-sol2

OmniOS-r151032% gld --print-output-format
elf32-i386-sol2

OmniOS-bloody% gld --print-output-format
elf64-x86-64-sol2

The build was successful in all cases.
