            Bug ID: 41305
           Summary: --rename-section flags should be case insensitive
           Product: tools
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: llvm-objcopy/strip

GNU objcopy accepts section flags with upper or lower case:

C:\Work\TempWork> objcopy --rename-section=.text=.foo,CONTENTS bar.o bar2.o
is equivalent to
C:\Work\TempWork> objcopy --rename-section=.text=.foo,CoNTenTs bar.o bar2.o
and
C:\Work\TempWork> objcopy --rename-section=.text=.foo,contents bar.o bar2.o

llvm-objcopy only accepts lower-case:
C:\Work\TempWork> llvm-objcopy --rename-section=.text=.foo,CONTENTS bar.o
bar2.o
llvm-objcopy.exe: error: Unrecognized section flag 'CONTENTS'. Flags supported
for GNU compatibility: alloc, load, noload, readonly, debug, code, data, rom,
share, contents, merge, strings

For compatibility we need this behaviour.
