I'm trying to build our application using GNU Toolchain and currently facing compilation issue with __asm directive; the error thrown is:
../../NRF51_SDK_v6_1/nrf51822/Source/bootloader_dfu/bootloader_util_arm.c:30:7: error: expected '(' before 'void'
__asm void isr_abort(uint32_t reset_handler)
^
../../NRF51_SDK_v6_1/nrf51822/Source/bootloader_dfu/bootloader_util_arm.c:74:19: error: stray '#' in program
LDR R0,[R0, #0x04] ; Load Reset handler into register 0.
^
../../NRF51_SDK_v6_1/nrf51822/Source/templates/gcc/Makefile.common:128: recipe for target '_build/bootloader_util_arm.o' failed
make: *** [_build/bootloader_util_arm.o] Error 1
The error is coming from line #30 bootloader_util_arm.c:
__asm void isr_abort(uint32_t reset_handler)
I'm using the Makefile.common, Makefile.posix under ~/NRF51_SDK_v6_1/nrf51822/Source/templates/gcc/ and application specific Makefile. More about the compiler, linker etc below:

Note:
1: Without the DFU-OTA specific files(bootloader_util_arm, dfu_app_handler.c, ble_dfu.c), I'm able to successfully build and flash(using JLinkExe for Linux), but I need the support for DFU-OTA in my application.
