    ld-elf/eh4: Pass -z max-page-size=0x200000 -z noseparate-code to ld

    -z separate-code creates separate code LOAD segment, aligns it to the
    maximum page size and places .plt section before .text section.  But
    ld-elf/eh4 passes -Ttext 0x400 to linker to place .text section at
    address 0x400, which is impossible for linker to accomplish:

    $ ld -shared -Ttext 0x400 -z separate-code -o x.so eh4.o
    ld: section .eh_frame LMA [0000000000200000,000000000020006b] overlaps
section .plt LMA [0000000000200000,000000000020001f]

    Since ld-elf/eh4 also checks exact addresses, this patch passes
    -z max-page-size=0x200000 -z noseparate-code to ld.

        PR ld/22845
        * ld-elf/eh4.d: Pass -z max-page-size=0x200000 -z noseparate-code
        to ld.
