ld: use a specific linker script in BPF targets

This patch makes the elf64bpf emulation to use it's own linker script,
based on elf.sc.  At the moment, the only change is that the BPF
executable doesn't define an entry symbol (BPF programs feature
several entry points scattered in several sections.)

This is a step towards the goal of generating proper ELF executables
that would be loaded by the kernel's libbpf.  We are not there yet:
BPF "programs" should still be linked with -r.

This change removes a warning while linking executables, decreases the
number of unsupported tests in the target from 47 to 29, and increases
the number of expected passes from 104 to 145.

Regtested in x86_64 for all targets.
No regressions.

ld/ChangeLog:

2019-08-07  Jose E. Marchesi  <jose.marchesi@oracle.com>

	* scripttempl/elf64bpf.sc: Adapted from elf.sc.
	* emulparams/elf64bpf.sh (SCRIPT_NAME): Use elf64bpf.
	(EMBEDDED): Define.
	* testsuite/ld-bpf/call-1.d: Do not expect a warning regarding an
	undefined entry symbol.
	* testsuite/ld-bpf/jump-1.d: Likewise.
	* testsuite/ld-undefined/undefined.exp: Do not pass '-e entry' to
	ld in BPF targets, and do not expect line number information.
	* testsuite/ld-srec/srec.exp (run_srec_test): xfail s-record tests
	in BPF targets.

+# When adding sections, do note that the names of some sections are used
+# when specifying the start address of the next.
+#
+
+#  Many sections come in three flavours.  There is the 'real' section,
+#  like ".data".  Then there are the per-procedure or per-variable
+#  sections, generated by -ffunction-sections and -fdata-sections in GCC,
+#  and useful for --gc-sections, which for a variable "foo" might be
+#  ".data.foo".  Then there are the linkonce sections, for which the linker
+#  eliminates duplicates, which are named like ".gnu.linkonce.d.foo".
+#  The exact correspondences are:
+#
+#  Section	Linkonce section
+#  .text	.gnu.linkonce.t.foo
+#  .rodata	.gnu.linkonce.r.foo
+#  .data	.gnu.linkonce.d.foo
+#  .bss		.gnu.linkonce.b.foo
+#  .sdata	.gnu.linkonce.s.foo
+#  .sbss	.gnu.linkonce.sb.foo
+#  .sdata2	.gnu.linkonce.s2.foo

+#  .ldata	.gnu.linkonce.l.foo
+#  .lbss	.gnu.linkonce.lb.foo
+#
+#  Each of these can also have corresponding .rel.* and .rela.* sections.
