-     around bugs in some toolchains.
-
-     Each TLS block from the objects available at link time has a size
-     and an alignment requirement.  The GNU ld computes the alignment
-     requirements for the data at the positions *in the file*, though.
-     I.e, it is not simply possible to allocate a block with the size
-     of the TLS program header entry.  The data is layed out assuming
-     that the first byte of the TLS block fulfills
-
-       p_vaddr mod p_align == &TLS_BLOCK mod p_align
-
-     This means we have to add artificial padding at the beginning of
-     the TLS block.  These bytes are never used for the TLS data in
-     this module but the first byte allocated must be aligned
-     according to mod p_align == 0 so that the first byte of the TLS
-     block is aligned according to p_vaddr mod p_align.  This is ugly
-     and the linker can help by computing the offsets in the TLS block
-     assuming the first byte of the TLS block is aligned according to
-     p_align.
-
-     The extra space which might be allocated before the first byte of
-     the TLS block need not go unused.  The code below tries to use
-     that memory for the next TLS block.  This can work if the total
-     memory requirement for the next TLS block is smaller than the
