[PATCH 4/6] [AArch64-4.7] Fix warning - aarch64_trampoline_init passes the wrong type to emit_library_call.

[James Greenhalgh]

Hi,

emit_library_call takes an `enum library_type` as its second argument.
Currently aarch64-4.7-branch passes it an int 0.

This patch fixes this, mirroring trunk, by passing LCT_NORMAL instead.

This patch fixes the warning:

config/aarch64/aarch64.c: In function ‘aarch64_trampoline_init’:
config/aarch64/aarch64.c:3893:8: warning: enum conversion when passing argument 
2 of ‘emit_library_call’ is invalid in C++ [-Wc++-compat]

Regression tested on aarch64-none-elf with no regressions.

OK for aarch64-4.7-branch?

Thanks,
James
