Commit Message
As the comment in the code says, TLS_IE needs only one dynamic reloc.
But commit b67a17aa7c0c ("LoongArch: Fix the issue of excessive
relocation generated by GD and IE") has incorrectly allocated the space
for two dynamic relocs, causing libc.so to contain 8 R_LARCH_NONE.
Adjust tlsdesc-dso.d for the offset changes and add two tests to ensure
there are no R_LARCH_NONE with TLS.
