configure: fix arm inline asm checks

Commit 8c893aa3cd5 removed quotes that were required to detect
inline asm in clang:

check_insn armv5te qadd r0, r0, r0
.../test.c:1:34: error: expected string literal in 'asm'
void foo(void){ __asm__ volatile(qadd r0, r0, r0); }

The correct code is:

void foo(void){ __asm__ volatile("qadd r0, r0, r0"); }
