*	x86_64: fix static build of __memcpy_chk for compilers defaulting to PIC/PIE	Aurelien Jarno	2016-11-24	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \|	When glibc is compiled with gcc 6.2 that has been configured with to default to PIC/PIE, the static version of __memcpy_chk is not built, as the test is done on PIC instead of SHARED. Fix the test to check for SHARED, like it is done for similar functions like memmove_chk. Changelog: * sysdeps/x86_64/memcpy_chk.S (__memcpy_chk): Check for SHARED instead of PIC.
