[risc-v] JAL overflow with linker relaxation

[quic-seaswara]

cat > jal1.t << \!
SECTIONS {
.baz : { *(.baz) }
. = . + 0x100000 - 0x100;
.foo : { *(.foo) }
}
!

cat > a.s << \!
.section .baz,"ax",@progbits
.global baz1
baz1:
call foo
.global baz2
baz2:
.align 16
call foo
.global baz3
baz3:
call foo
!

cat > b.s << \!
.section .foo,"ax",@progbits
.global foo
.p2align 12
foo:
nop
!

clang -c -target riscv64 b.s a.s
ld.eld a.o b.o -T jal1.t -Map x

Error: a.o:(.baz+0x10000): relocation R_RISCV_JAL out of range: 1048576 is not in [-1048576, 1048575]; references 'foo'

Linker produces a relocation overflow error by relaxing foo to jal and later realizes that it does not fit because the distance increases after align relocations get handled.

This is a simplified usecase from building the linux kernel on riscv64.
