ld: testsuite: Fix no-plt tests on Solaris/i386
Several no-plt tests FAIL on 32-bit Solaris/x86:
FAIL: Build libno-plt-1b.so
FAIL: No PLT (dynamic 1a)
FAIL: No PLT (dynamic 1b)
FAIL: No PLT (dynamic 1c)
FAIL: No PLT (PIE 1e)
FAIL: No PLT (PIE 1f)
FAIL: No PLT (PIE 1g)
The failure mode is always similar, e.g.
../binutils/objdump -dwrj.text tmpdir/libno-plt-1b.so > dump.out
regexp_diff match failure
regexp "^ +[a-f0-9]+: 8b 80 ([0-9a-f]{2} ){4}[ ]+mov +-0x[a-f0-9]+\(%eax\),%eax$"
line " 4aa: 8b 80 14 00 00 00 mov 0x14(%eax),%eax"
regexp_diff match failure
regexp "^ +[a-f0-9]+: ff a0 ([0-9a-f]{2} ){4}[ ]+jmp +\*-0x[0-9a-f]+\(%eax\)$"
line " 4ca: ff a0 14 00 00 00 jmp *0x14(%eax)"
i.e. there's a positive offset from the GOT instead of the expected
negative one. AFAICS that's because there are additional GOT entries on
the Solaris side (printed with elfdump -G since there seems to be no
support for that in either readelf or objdump):
* Solaris/i386:
Global Offset Table Section: .got
index addr value pending relocation
[0] 0x15f4 0x1514
[1] 0x15f8 0
[2] 0x15fc 0
[3] 0x1600 0x3a6 R_386_JMP_SLOT __cxa_finalize
[4] 0x1604 0 R_386_GLOB_DAT _ITM_deregisterTMCloneTable
[5] 0x1608 0 R_386_GLOB_DAT func
* Linux/i686:
Global Offset Table Section: .got
index addr value pending relocation
[0] 0x3fe0 0 R_386_GLOB_DAT _ITM_deregisterTMCloneTable
[1] 0x3fe4 0 R_386_GLOB_DAT __cxa_finalize
[2] 0x3fe8 0 R_386_GLOB_DAT __gmon_start__
[3] 0x3fec 0 R_386_GLOB_DAT func
This patch fixes this by making the sign optional in affected cases.
Tested on i386-pc-solaris2.11 and i686-pc-linux-gnu.
