Qualcomm DSP binary is prepared by combining different ELFs'.
This patch differentiates the section header name of ELF within
the same existing section headers of the same ELF.

Example readelf output of DSP binary:
    [60] .start.ac_bin_process PROGBITS
    [61] .resource_table.ac_bin_process PROGBITS
    [62] .comment.ac_bin_process PROGBITS
