[osv-dev] [PATCH] dynamic linker: fix the old bug in the logic to calculate the ELF base

there are multiple PT_LOAD and non-PT_LOAD headers sharing the same p_vaddr value, it ends up using wrong header and then overwriting other segments data. This patch fixes it by separating filtering of PT_LOAD headers and indentifying the lowest and highest ones. Signed-off-by: Waldemar Kozaczuk
