ltp: set -fomit-frame-pointer explicitly for x86-64
Since ltp contains x86-64 assembler which uses the
frame-pointer register, it will trigger below error
when build ltp with -fno-omit-frame-pointer on
x86-64.
| cve-2015-3290.c: In function 'child_thread':
| cve-2015-3290.c:416:1: error: bp cannot be used in asm here
And there is also some comment as below in the source
file ltp/20180515-r0/git/testcases/cve/cve-2015-3290.c
* Build with -O2. Don't use -fno-omit-frame-pointer.
So explicitly set -fomit-frame-pointer on x86-64 for
compiler to fix the above build error.
