## Check that obj2yaml dumps SHT_STRTAB/SHT_SYMTAB/SHT_DYNSYM sections
## when they are allocatable.
## In the following test we check the normal case: when .dynsym (SHT_DYNSYM)
## and .dynstr (SHT_STRTAB) are allocatable sections and .symtab (SHT_SYMTAB),
## .strtab (SHT_STRTAB) and .shstrtab (SHT_STRTAB) are not.
## Check we explicitly declare allocatable sections.
