i386: Accept both .plt.got and .plt.sec sections

    i386: Replace PREINIT_FUNCTION@PLT with *%eax in call

    Since we have loaded address of PREINIT_FUNCTION into %eax, we can
    avoid extra branch to PLT slot.

changed __gmon_start__ relocations in crt1.o from

00000015  0000092b R_386_GOT32X           00000000   __gmon_start__
0000001e  00000904 R_386_PLT32            00000000   __gmon_start__

to

00000015  00000a2b R_386_GOT32X           00000000   __gmon_start__

As the result, .plt.sec section may be generated instead of .plt.got
section, depending on __gmon_start__ relocations.

	* testsuite/ld-i386/plt-main-ibt.dd: Accept both .plt.got and
	.plt.sec sections.
