[mips] fix CRT_CALL_STATIC_FUNCTION macro
jal can not reach a target in different region, so replace it with
la/jalr variant.
New test has been added. It uses -Wl,--section-start=.init= and
-Wl,--section-start=.text= to put the two sections in different 256

Hi everyone,
This is a follow-up to a change [1] in glibc. It fixes the issue [2] when
jal can not reach a target in different region.
It has been tested with DejaGnu for mips32/o32, mips64/n32 and mips64/n64.
Let me know what you think.
Regards,
Petar
