To: edk2-devel
GCC tool chain uses -fpie in CC_FLAGS. So, add -pie in DLINK_FLAGS.

https://lists.01.org/pipermail/edk2-devel/2017-August/013508.html
3.13 Options for Linking
========================
'-pie'
Produce a position independent executable on targets that support
it. For predictable results, you must also specify the same set
of options used for compilation ('-fpie', '-fPIE', or model
suboptions) when you specify this linker option.
3.18 Options for Code Generation Conventions
============================================
'-fpie'
'-fPIE'
These options are similar to '-fpic' and '-fPIC', but generated
position independent code can be only linked into executables.
Usually these options are used when '-pie' GCC option is used
during linking.
'-fpie' and '-fPIE' both define the macros '__pie__' and
'__PIE__'. The macros have the value 1 for '-fpie' and 2 for
'-fPIE'.
