X86-64: Test external function reference without PLT
To call an external function, the direct branch to the PLT entry can be replaced by an indirect branch via the GOT slot, which is similar to the first instruction in the PLT slot. Instead using the PLT slot as function address, the function address is retrieved from the GOT slot. If linker determines the function is defined locally, it converts indirect branch via the GOT slot to direct branch with a nop prefix and converts load via the GOT slot to load immediate or lea, * testsuite/ld-x86-64/libno-plt-1b.dd: Likewise. * testsuite/ld-x86-64/libno-plt-1b.rd: Likewise. * testsuite/ld-x86-64/no-plt-1a.dd: Likewise. * testsuite/ld-x86-64/no-plt-1a.rd: Likewise. * testsuite/ld-x86-64/no-plt-1b.dd: Likewise. * testsuite/ld-x86-64/no-plt-1b.rd: Likewise. * testsuite/ld-x86-64/no-plt-1c.dd: Likewise. * testsuite/ld-x86-64/no-plt-1c.rd: Likewise. * testsuite/ld-x86-64/no-plt-1d.dd: Likewise. * testsuite/ld-x86-64/no-plt-1d.rd: Likewise. * testsuite/ld-x86-64/no-plt-1e.dd: Likewise. * testsuite/ld-x86-64/no-plt-1e.rd: Likewise. * testsuite/ld-x86-64/no-plt-1f.dd: Likewise. * testsuite/ld-x86-64/no-plt-1f.rd: Likewise. * testsuite/ld-x86-64/no-plt-1g.dd: Likewise. * testsuite/ld-x86-64/no-plt-1g.rd: Likewise. * testsuite/ld-x86-64/no-plt-check1.S: Likewise. * testsuite/ld-x86-64/no-plt.exp: Likewise. * testsuite/ld-x86-64/no-plt-extern1.S: Likewise. * testsuite/ld-x86-64/no-plt-func1.c: Likewise. * testsuite/ld-x86-64/no-plt-main1.c: Likewise.
