fix(fpga): avoid stripping kernel trampoline

The Arm FPGA platform builds a final AXF file, which is an ELF file
containing some required trampolines and binaries, like the DTB. This is
more a "container with load addresses" than an object or executable
file, but it's still built with the linker tool.
Commit acf0076ae2e5 ("build(fpga): correctly handle gcc as linker for
LTO") pulled in ${TF_LDFLAGS} when building this AXF file, which
includes "--gc-sections". That strips the kernel trampoline off that
file, making the board hang when the kernel is loaded at 0x80200000
(the recommended load address for "newer" kernels).

Drop the usage of TF_LDFLAGS altogether, since we need none of the
options specified there for our special linker step. Instead collect
the needed options (like -nostdlib) in a separate variable, and just
account for the slight syntax differences between GCC and clang.
"--strip-debug" turns out to be redundant, since "-s" already strips
more symbols, so remove that from the list.
