*/*/bsp_specs: Increase similarity to ease future analysis
Done:
arm
bfin
epiphany
i386
lm32
m32c
mips
moxie
nios2
or1k
powerpc
riscv
sh
sparc
sparc64
v850
To do:
m68k
Differences noted:
+ endfile was sometimes before startfile
+ endfile sometimes was hard-coded and did not have -qrtems version
+ Should -e XXX (e.g. entry point) be in linkcmds?
+ Should -u XXX (e.g. undefined symbols) be in linkcmds?
+ Typos: Odd spacing, "old_endfiles" typo, and *(old_endfiles) (not %)
+ nios2: Referenced crtnn.o not crtn.o (error)
Need to revisit:
+ m32c, moxie, sparc64 includes !nostdlib which is not used elsewhere
+ sh has -EL/-EB mapping. Why needed?
+ sparc64 didn't include crti.o/crtn.o but it is part of toolset
+ v850 uses something like this for link and end_file:
"%{qrtems: %(old_link)}"
This means that these are unnecessary. Try this on all.
+ mips uses old_link all the time also.
+ arm/tms750 adds -EB.
+ powerpc: Why do we have rtems_crt* and not use something from GCC?
Updates #3520.
