[PATCH v2 07/16] libdw: Fixes compile of dwarf_whatattr.c and dwarf_whatform.c

[Yonggang Luo via Elfutils-devel]

If __OPTIMIZE__ is defined, then compile  dwarf_whatattr.c and dwarf_whatform.c
will cause symbol conflict between
dwarf_whatattr.c and libdw.h,
dwarf_whatform.c and libdw.h,

So always undefined __OPTIMIZE__ when compiling these two files

The error message is:
dwarf_whatform.c

[build] C:\work\xemu\elfutils\libdw\dwarf_whatform.c(39,1): error: redefinition 
of 'dwarf_whatform'
[build] dwarf_whatform (Dwarf_Attribute *attr)
[build] ^
[build] C:\work\xemu\elfutils\libdw/libdw.h(1110,1): note: previous definition 
is here
[build] dwarf_whatform (Dwarf_Attribute *attr)
[build] ^
[build] 1 error generated.
