Pass linker search paths with -L not -Wl,-L, so they take priority over sysroot

This fixes link-time errors where the toolchain used was esp-open-sdk
built with the default STANDALONE=y (meaning there are Espressif SDK
libs in the sysroot).

NMIExceptionHandler: Don't save callee-saved registers, fix stack alignment
...
NMI routine sdk_wDev_ProcessFiq seems to be written in C, meets ABI
calling conventions for callee-saved registers. Not sure why SDK
handlers saved them.
NMI handler now also meets the ABI requirement that stack is 16 byte
aligned (doesn't seem strictly necessary, but can't hurt.)

Simplify interrupt and RTOS timer tick handlers
...
RTOS Timer tick handler is now the same as any other ISR.
This causes a few subtle behaviour changes that seem OK but are worth noting:
* RTOS tick handler sdk__xt_timer_int() is now called from one stack
frame deeper (inside _xt_isr_handler()), whereas before it was called
from the level above in UserHandleInterrupt. I can't see any way that
the extra ~40 bytes of stack use here hurt, though.
* sdk__xt_timer_int() was previous called after all other interrupts
flagged in the handler, now it's called before the TIMER FRC1 & FRC2
handlers. The tick handler doesn't appear to do anything particularly
timing intensive, though.
* GPIO interrupt (value 3) is now lower priority than the SPI
interrupt (value 2), whereas before it would have been called before
SPI if both interrupts triggered at once.
