add LLD support
this commit adds LLD support by removing all INFO sections. LLD kind of supports INFO in the form of
NOLOAD but when the linker script contains NOLOAD sections LLD emits a binary with false `size`
information: for example, it reported a fake increase of 20KB in .text and a fake increase of 1KB in
.bss when compiling a program that only allocates a single Box.
As the INFO sections are gone we can no longer support the stack overflow protection added in #43 so
all the other related changes, like making _stack_start overridable, have been removed as well.
If you want to continue using stack overflow protection you can stick to v0.3.x.
As the .debug_gdb_scripts output section has been removed from the linker script these changes will
only reliably support both LD and LLD if/when rust-lang/rust#49728 lands.
closes #53
